Title: Looking for a new PSU.
Post by: JacksRag(e) on Wednesday, February 27, 2008, 07:29:53 PM
So I just got an 8800 GT yesterday, but have been holding back on installing it because of my weak ass PSU.  I've been looking around for sales on different PSUs and found this one (http://Antec Basiq 500 Watt Power Supply).
What are your thoughts on this?  My current power supply just doesn't have enough amperage on the +12V rail (18A single rail, when the minimum is 26A).  This has two +12V rails at 18A, now I'm not too sure if you can add them up and use that, or if I'm just being a simpleton about the amperage.  Anyway, thanks for any advice in advance.

I never even knew you had to look all that deeply into the individual rails.  But look like you picked an Antec, so that's a good start. 

BTW, your link doesn't work.  The URL you have there is... weird.

Congrats on the 8800GT Hooby!

I'd say any brand name 550Watts would be more than sufficient. Recently, whenever I would start any game -- even chesss -- my computer would just instantly lose complete power. Turned out that my 5 year old Antec 500 was about dead, so I had to get a new one. This is what I got:

By the way, I hear really good things about this:

See if you can get that Corsair PSU. Got some solid reviews. I was going to get that initially, but it was out of stock, so I had to opt for the Asus.

How odd....the link I copied must have been..tampered with?  Dunno.  That's the one I'm looking at, though. hmm.

And I'll take a look at the other psus, too, pug.  The thing is I'm trying to keep this under a budget, this was a pricey little item and what with Patapon, Jeanne D'arc, Katamari, Disgaea already bought and then God of War and Smash Brothers next week..I don't know if I can afford much now.  ARGH.

That's probably good. There was a website somewhere that not only had a breakdown of various PSUs but a little flash app where you could imput all your components and it would tell you what you could get away with.  I'll see if I can track it down.

I'm personally using a 450W, which isn't a problem, but might require an upgrade if I go 8800GT (I'd have to see what the power draw difference is between it and my current card).  I've always been told that the watts isn't the most important factor, but rather a combination of the brand and the watts.  Some cheaper PSUs may be rated for 500 or 600, but could crap out before that because they don't provide 'clean' power.  No, I don't really know what that means at all.  Now leaving thread.
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Thursday, February 28, 2008, 12:03:01 AM
From all the research on the cards and whatnot, I've found that more important than the wattage of the psu it's the amperage.  If I remember, you have a 7900 gt, right?  You're ok on wattage, because even at high loads, the 8800gt is more efficient than the gts or gtx.  You're gonna want to check your +12V amperage, though.  You could have 500 or 600 watts, but if you don't have enough amperes going through the +12V rail, you're bottlenecking the card and also putting the card and your system at risk.

This clean power you're talking about, I think, has to do with the stability of the voltage and whatnot.  If your psu is rated at a certain wattage or voltage, but it dips back and forth, you're gonna be stuck with one unstable rig where it might reboot when the power dips and stuff...yea, that's as far as I understand it.  Eh.

And oh yea, the brand is important too.  I've consistently seen Corsair, Antec, Coolermaster, Rosewill seems to be well regarded on newegg,

You're saying what matters most is current capacity at the +12V rails, right?  Because on paper at least, once you're in the DC circuitry, P=IV (power = current * voltage, or watts = amps * volts).  That does get complicated when you go over to the AC side, and of course, the power rating of the PSU is what it sucks out of your AC outlet.  It gets into calculus, which I've forgotten and I like it that way.  Suffice it to say that the actual AC power drawn is somewhere between a half and 3/4 of volts*amps, depending on magnetic fields, induction, and other such shit I don't want to think about.  In any case, given a fixed voltage, amps are directly proportional to watts.  So unless something besides the +12V rails is drawing lots of current away in the PSU, once you know the wattage is good, the amperage should be good as well (and vice-versa).  So it would seem anyway.

Post by: JacksRag(e) on Thursday, February 28, 2008, 04:08:44 AM
Mmm, well what matters most when it comes to the newer generation of cards and those of us with older generation psus, more like.  My psu, from research and other folks' accounts, is nothing more than a 330 watt psu rebranded as 430 watts.  Sure, it could push out 430 watts under peak load, but it wouldn't hold up for extended amounts of time.  All this crap is unduly complicated. 
And cobra..that whole post scared me.
Well, from how I've come to understand it, the newer power supplies have dual +12v rails with 18 amperes across each rail.  Some of that goes to the cpu and the rest goes to peripherals.  My psu is single railed, so that 18 amperes is nowhere near enough to power the new card.
Buh.

Well, from how I've come to understand it, the newer power supplies have dual +12v rails with 18 amperes across each rail.  Some of that goes to the cpu and the rest goes to peripherals.  My psu is single railed, so that 18 amperes is nowhere near enough to power the new card.
Buh.

OK, so the problem is that the current capacity of the rail isn't high enough?  Keep in mind that the current drawn from each rail varies.  18 is just a limit.  If one rail draws much less current, there will be more power available to deliver current to the other rail.  But if the current capacity of the rail used for the video card is too limited, you're right.  It won't work right, regardless of the PSU's power rating, or power use through the other rail. 

Don't forget, though, that at a fixed voltage (12V here), there is a fixed max amount of current that can be delivered from a given power rating, regardless of how many rails you get.  I'm not sure why the number of rails would even matter, as long as the whole capacity of the PSU is made available to whatever you hook up to it.  If 18 amps is the overall limit, the max power draw can be figured out.  (See the formulas above.)  If that power number falls way below the PSU's rating, then the rating is a lie.  No?  Let's apply it here.  12V * 18A = 216 VA.  In a DC circuit, 216 VA = 216 watts.  That's all you can get out of a PSU at 12V with an 18-amp current limit.

Here's where I need to punt, though.  When you take that DC wattage over to its AC generation, it gets away from me.  There's all the shit I mentioned before, and there are conversion inefficiencies as well.  It could well be that it takes 450 AC watts to deliver 216 DC watts.  Seems like a huge loss to me, given that to get 450 watts AC, you need something like 800 VA AC.

You know what?  You're right.  You're absolutely right.  After trying to work through all this while posting, I've realized that to rely on the AC power rating doesn't get close enough to what you need to know.  You need to know the requirements of your card, and if current capacity at the molex plug tells you the whole story, you're better off.  So what is the max current draw of that card?
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Thursday, February 28, 2008, 04:27:21 PM
The manufacturer recommends a psu with at least 26 amperes across the 12 volt rail(s).  My old psu had a max of 18A across a single rail, enough to power the cpu and other peripherals, but not stable enough when you add in the 8800gt.  So, I ended up getting the Antec with 2 +12v rails at 18A each, giving me some decent headroom with 36A across the rails.  I installed it earlier and I've been chugging along quite well.  CoD4 and Bioshock look amazing maxed out, though I can barely play Crysis at medium settings at 1248x1024.  Buh.  Yea, I was with you for a while too, cobra.  But damn it, once you got into AC you lost me.  haha...thanks.
Title: Re: Looking for a new PSU.
Post by: Cobra951 on Thursday, February 28, 2008, 05:43:02 PM
Oh, but now I'm confused again.  If your card is hooked up to one rail, and that rail has an 18-amp limit, who cares that the PSU can deliver a total of 36 amps?  How does that help the card at the 18-amp bottleneck?

Edit:  Is the point that 18 amps is enough, as long as everything else is hooked up to the other rail?  It would still be nice to know what the card's max current requirement is.
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Friday, February 29, 2008, 12:07:07 AM
What I found is that with multiple rails, the amperage adds up.  So, originally my single 12v rail gave out 18A.  But with my dual 12v rail, I get a total of 36A.  The minimum for amperage is 26A as stated, but I haven't been able to find the max requirement for current.  And I think that current is outputted as needed by the component.  So you've got the cpu pulling some current, and then most of the new cards come with the 6-pin molex converter that splits into two 4-pin molex plugs.  I've heard it's recommended to plug in a 4-pin molex from both rails so as to let the card draw the current when needed too. 
The thing with my new psu is that there's an actual 6-pin molex plug on it so that I just plugged it directly into the card instead of using the converter.  It's run well so far, so I'm not sure if I should go ahead and put the converter back in.  I might run some benchmarks and see if it makes a difference.  I'm just lazy at the moment.

Post by: WindAndConfusion on Friday, February 29, 2008, 01:45:36 AM
I'll ignore all the fucked up physics in this thread and just comment on the last post:

If you're connecting two 18 amp rails in parallel, that gives you 36 amps total. 36 amps at 12 VDC is 432 watts, which is roughly what your power supply is rated at. 26 < 36, so you're OK.
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Friday, February 29, 2008, 03:18:54 AM
Basically, yea.  A lot of the power supplies are a bit deceiving in their descriptions.  They'll say 500 or 430 watts, but that's just the peak wattage and it's really not all that sustainable.  Have it running at max and you run the risk of frying the unit.  I'm sure I've got some things wrong and misunderstood in the thread, but I did learn a few things.  And my card's flying right now.
Except in Crysis.  Damn you, Crysis.

Title: Re: Looking for a new PSU.
Post by: Cobra951 on Friday, February 29, 2008, 02:58:10 PM
Haha!  A²+B²=C² is actually very pertinent.  In AC circuits, apparentPower² = realPower² + reactivePower², or VA² = watts² + VAR².  VA is volt-amperes, which you get from the simple DC equation P=IV.

I did learn all about the simpler equations in physics class.  I took 9 hours at OSU.  The AC complications I learned about way after, the first time I looked into uninterruptible power supplies.  They have a VA rating, and a watt rating which is much lower.  That intrigued me, so I looked it up.  The equations get into calculus--you have to do an integral, and that I've left way behind.  I hated freaking calculus.  (I took 12 hours of that.)

Post by: gpw11 on Saturday, March 01, 2008, 03:09:17 PM
Did you ever figure out if you can add the 12V rails together?  Because upon checking mine, I have two both rated at 18A.  Combined, they're more than enough, but obviously they fall short individually. 

I've also looked at some newer ones, and most still seem to use 18A 12V rails, but have three or four of them as opposed to the two mine has. 
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Saturday, March 01, 2008, 03:31:21 PM
Yea, I found that what matters is the total number of amps you have.  You should be good with the number of amps for a 8800gt.  Not nearly good enough for SLI though.
Does your psu have a dedicated pci-x pin?  I noticed a lot of newer psus have one of those now.
Title: Re: Looking for a new PSU.
Post by: Cobra951 on Saturday, March 01, 2008, 04:13:44 PM
In order to add up the amperage capacity, the rails need to be hooked in parallel to your card.  W&C mentioned that, but is it possible?
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Saturday, March 01, 2008, 04:33:29 PM
Yea, it's recommended that if you use the 6-pin to double 4-pin converter that comes with the newer cards, you should plug in the 4-pin molex from the different rails.  My PSU had two sets of 4-pin molex plugs on separate cables, I assume that I should plug in one 4-pin from each cable.  That's what I gathered.  But fortunately, my psu also has a 6-pin molex plug, making the converter unnecessary.
Title: Re: Looking for a new PSU.
Post by: Cobra951 on Saturday, March 01, 2008, 04:41:33 PM
If you can skip an extra plug, you are definitely better off.  No possibility of excess heat in a pressure connection.  That's wild, though, 36 amps.  Haul out your car battery, and hook the video card up to that.
Title: Re: Looking for a new PSU.
Post by: JacksRag(e) on Saturday, March 01, 2008, 06:03:51 PM
I know, right?  And the 8800gt is fairly efficient compared to the big guns.  Imagine the current for a pair of 8800gtx ultras in SLI.

Sweet, thanks.  I don't know how I read right over that the first time.

and yeah, it's kind of insane how much power these things require.  I did, however, find that calculator (http://www.extreme.outervision.com/psucalculatorlite.jsp) I was talking about (actually, a different one that does the same thing), and it figures that at 90% load, I'll be using just under 350W   at 90% load.  That's with some upgrades I don't have at the moment.    So, I figure I should be more or less good with a buffer zone of 100W or so.

And that's why I think it's retarded when people compare Crytek to ID, Epic, or even Valve.



I think I was the only one who compared Crytek to those companies on these forums :P.

You are partially correct on the lack of scaling, but the rest of it, I disagree with. I know you were being facetious with the SLI comments, but here is what I think: 

1. I am getting an average of 25 fps at a resolution of 1440x900 on high settings using a system not significantly better than this. (http://kotaku.com/345278/crytek-specs-out-an-affordable-crysis-pc) That PC you can build on NewEgg without the Windows CD for about $750. The system was recently tested on Maximum PC with Crysis running on high on a 19'' monitor, and earning 30+fps second. So yea, the quad SLI thing is normally something echoed by console gamers with a bone to pick.

2. a) You mention ID software, but keep in mind that similarly to Epic or Valve, they have never released a cutting edge engine that rendered anything other than closed environments.

b) When Quake III was released, fanboys were in an uproar of Crysis proportions, because the game ran like ass on even the most modern of systems at maximum settings. That was something the Quake fans weren't expecting, and it took nearly a year for technology to catch up with Q3. The problem with Crysis has been the marketing, and the fact that ATi pushed the GPU market a year behind schedule.

c) People forget that the Xbox 360 is capped at 30 fps in its shooters. So isn’t getting the same on a PC (that also has to shoulder Windows) just as acceptable? The only point where you can compare Epic or Valve to Crytek is in the internal environments, of which are many in Crysis. In the underground settings of Crysis, I found the game looked technically better than Unreal Tournament 3, and was running at over 80 frames per second.

3. On that $750 machine I pointed out, PC Gamer magazine benchmarked Crysis on medium settings and were getting an average of 58 frames per second. You might argue that Crysis on medium doesn't look nearly as good as high, but it still looks gorgeous. In fact at medium Crysis looks better than Gears of War, Half-life 2, Halo 3 and Doom 3. Of course there is little comparison to those static environments, because Crysis renders gorgeous terrains with dense foliage affected by environmental effects in real time; trees sway, leaves rustle, water ripples etc. When you compare Doom 3 or Unreal Tournament to Crysis, the only life you will see from the former two, is in the form of enemy AI, limited object destruction (read: crates), and physics. 

The only games that can be compared to the open ended environments of Crysis are Operation Flashpoint, Ghost Recon, Oblivion, and S.T.A.L.K.E.R. All of those look worse than anything in Crysis, and ran each poorly at launch. The best of the bunch is Oblivion, which at max settings runs at 30fps on my system, yet pales in comparison to Crysis.
Finally, have a look at the screenies I took. Some of that looks near photorealistic, don’t you think? And it feels even better when played through. If you look at pretty screenies from Epic or ID games, the still frames will be about as static as the actual game.

I think the problem for you was Vista 64. It had some massive issues with the game, which is the only reason I can come up with in your case.

I'll post the fraps results tomorrow, but basically at medium settings I am getting over 60 fps (vsynced at 60) in normal conditions. During firefights it goes down to 50-55 fps in Vista, and between 40-50 in really intense battles. Is smoother in XP by 8-12 fps average. That matches the results PC Gamer published in their mag, who stated that with an 8800GT at medium settings they were getting about 57 fps.

As for how it looks at medium, I disagree in that I think it looks pretty damn good, but its a matter of perspective really. We just have different opinions on this, and I guess it is a personal thing. I just have to say, and it is something that you may or may not agree with, at medium the game looks insanely better than S.T.A.L.K.E.R. Have you played that?

I also think technically Crysis at medium looks better than Gears of War or Unreal Tournament 2007.

In the end, I do agree that Crysis could have used with better optimization on medium, but I find it performs much better for me in XP.

I have some work to do, or I'd be posting the fraps screenies. Will post them tomorrow for sure.

Also I apologize to hoob for the thread hijack.

I definitely disagree that Crysis on medium looks better than UT3 or GoW.  Maybe S.T.A.L.K.E.R., but that was a game that should have released two years ago.

Here's the thing that really puts me off:  FarCry had amazing performance for the visual acuity of its engine, and Crytek was rightly lauded for its efforts.  I feel like Crysis is the opposite.  It's a visually impressive game (on high or very high settings, anyway), but not so much so as to explain the extremely poor performance.

I feel that its engine is on par with the UT3 engine in most respects and games that run on the UT3 engine run worlds better than Crysis does.

And what sort of "massive" problems were there on Vista x64?  I ran the game on that and the only problems I had were performance-related.  I was able to run the game respectably on high settings at the lowest widescreen resolution (1400x900?)

c) People forget that the Xbox 360 is capped at 30 fps in its shooters.

Yep, me again, with the obligatory counterpoint.  There is no such mandatory cap.  If you want to see what the console can do at 1280x720 at 60 vsynched fps, see the Burnout Paradise game or demo on a friend's 360.  Developers may shoot at a 30fps target to double their per-frame rendering budgets.  That's their prerogative.

I wasn't concerned with what the 360 can or can't do, even if it might have come across as such. We were discussing frame rates, and my point was regarding gamers who find it perfectly acceptable to play shooters at 30 fps on their 360s, yet complain (on other forums, not you guys) about being unable to get 100+ fps in games like Unreal Tournament, Crysis, Doom III etc. In fact Doom III's frame rate on the PC was initially targeted at 30 fps by Carmack, yet PC fans were pretty unhappy, accustomed to over a 100 fps on Quake. 

I cited the 360 as an example not because I was trying to say it was teh weak or incapable, but because I was pointing out how gamers found a cap of 30 fps acceptable. If you look at the context of that post, you will note that I was just talking about frame rates and stuff. Not that I am saying that you took it that way or anything. I know you are just pointing out that the 360 is capable of more than 30 fps, which I realize. I am just clarifying regardless. :)

I wish I had S.T.A.L.K.E.R. (god I hate the artificially abbreviated names) installed, so I could post comparative screenies. The game's textures up close looked like ass.

UT3 and GoW feature closed environments with no calculations being made other than the character to character interaction. The outdoor worlds rendered in the unreal engine are just a series of closed levels, with 3D tricks in the background that make the environment seem large scale. I think the developer of COD4 was talking about how they've basically got background images to create an illusion of a vast environment. In fact if you look at COD4 or GoW, those games are a series of restricted areas. 

I actually haven't played Enemy Territory, so I can't really comment on that.

Basically I feel that the game that compares to Crysis is Oblivion, and it performs similarly, if not worse.

At the same time, while I find Crysis is a better looking game at medium settings, I guess there isn't really a technical comparison between it and games powered by the Unreal Engine. They are both designed for different purposes in mind, and are good at what they are meant to do.

We've talked about this a couple of times before, and I've posted links previously :P. Basically the massive problems I refer to were performance related. I think they've been fixed through Windows Update.

Crysis 25 percent slower on Vista 64 bit

We just wanted to prove that Nvidia's driver for Vista 64 bit is definitely far behind the Windows XP driver. We compared Forceware 169.12 for Vista 64 and 169.09 for XP.

We tried the same demo under Windows XP and Vista 64 bit with the same hardware. The test machine was equipped with two Athlon FX74 CPUs at 3GHZ, 4GB of Corsair 8500 memory and two Raptor drives.

In Vista 64 bit, it turns out that you get only 26.51 FPS average with all settings at high, 1280x1024 with 4X FSAA and 8X Aniso. This is the best that Vista 64 can do for you. This is probably the lowest resolution you expect from Geforce 8800 Ultra overclocked card.

It wouldn’t be so bad if the same demo and the retail game itself at same settings score 34.83 FSP or some 25 percent better score under “old” XP. Under XP, the minimal score is 18.84, while under Vista 64 bit you get 7.9 as a minimal FPS.

In Windows XP, the maximum score is 44.51 while under Vista 64 with Nvidia Forceware 169.12 for Crysis the maximal score is 35.51.

To make the situation even worse, you cannot get anything close to playable frame rates in Vista 64 at 1280x1024 at very high settings and using this resolution. Nvidia had better fix these drivers, as Microsoft wants to sell more copies of its Windows Vista operating system, and after this there will be barely anyone who will choose to play Crysis in Vista 64 bit.

Yea it should have been better. I found it pretty good (on XP) till the last battle

. The performance there was below par at the final battle for me.

The CryENGINE2 was first licensed out to French company IMAGTP who specializes in architectural and urban-planning communication. The purpose of licensing the engine was to create a program to allow clients to see exactly what a building or other structure would look like before any actual building was undertaken.

As of March 7, Avatar Reality, Inc., a new development studio, has licensed the CryENGINE2 out to use on a Massively Multiplayer Virtual World (MMVW) that takes place on a terraformed Mars.[1]

On May 11, 2007 Crytek announced that they would be using the engine to create a game based on their new Intellectual Property. The new game is rumored to be a Playstation 3 and Xbox 360 game based on an interview in which Crytek CEO Cevat Yerli said that it would be. It is also confirmed that it will not be a port of Crysis and in fact will not even be a first person shooter.

On the 17th of September, 2007, Ringling College of Art & Design became the first higher education institution in the world to license CryENGINE2 for educational purposes.

I find it cool as a gamer, than an engine familiar to us for violent fun can be used for such purposes.

Nvidia recently released a new Vista x64 driver, but I was sad to see that all it did was add support for the 9600.

I can't imagine CryEngine 2 will power a 360 game.  It would crush the 360.  The motherboards would be so warped they would be popping out of the case!

Well apparently the 176 mb patch supposedly added 10fps to Vista 64. You didn't find much of an improvement? Actually Crytek said that Vista 64 (a few months before they launched the game) was actually going to be taken advantage of 64 bit bla bla bla, and run 15-20% faster. All of that was talk I guess.

As for it coming to consoles:

I think I was the only one who compared Crytek to those companies on these forums :P.

You are partially correct on the lack of scaling, but the rest of it, I disagree with. I know you were being facetious with the SLI comments, but here is what I think: 

1. I am getting an average of 25 fps at a resolution of 1440x900 on high settings using a system not significantly better than this. (http://kotaku.com/345278/crytek-specs-out-an-affordable-crysis-pc) That PC you can build on NewEgg without the Windows CD for about $750. The system was recently tested on Maximum PC with Crysis running on high on a 19'' monitor, and earning 30+fps second. So yea, the quad SLI thing is normally something echoed by console gamers with a bone to pick.

http://www.anandtech.com/video/showdoc.aspx?i=3183&p=3

Triple SLI, 40fps, 1920 x 1200, no AA.  This isn't the article I originally read about this on, but there's a reason that people bring this up.  That's $600+ for the GPUs alone for not much in the way of performance.

But seriously, do we have to get into this?  I get where you're coming from and don't entirely disagree (except for the whole thing about the game looking nice and being marginally playable at the same time...even on medium.  You either give up one or the other), but no one is ever going to convince anyone else in a thread like this.

Yes, but isn't that the immaturity of triple SLI, and basically Nvidia's issue? Isn't that about as well as triple SLI functions? At a monstrous resolution of 1920 x 1200, they are getting 25 fps on a single 8800 card. It is a bit like blaming the price of petrol on the car.

On an Xbox 360 with 40% less the resolution gamers are happy with 30 fps, so what's wrong with 25 fps?

Yes that's technically correct, but that's like saying you have to buy a Ferrari to enjoy the road.

Don't you think it is weird that three cards aren't yielding even twice the performance of a single one? If you look at the performance of other games like Oblivion, WiC on the same graph you posted, they aren't getting frame rate boosts after the second SLI either, so is this really a Crysis issue or an Nvidia problem?

Also when there are two SLI cards used, the frame rates are at 42, and at three they are 43. So why would someone pay $600 for 1 more fps? In reality, the third SLI card isn't being utilized.

But like you yourself have stated before, those $600 GPUs are targeted at the luxury crowd. You know the Intel Quadcore QX6850 is priced at $1200, while the Q6600 is $350. The price difference is of $900, yet the Q6600 is very close in gaming benchies. You aren't seeing anyone say people need to spend over a grand on a QX6850 to enjoy PC gaming though.

But back to the 8800ULTRA. It performs what, 10% faster than the 8800GT priced at $220? So isn't saying Crysis needs the $600 card misleading?

Two 8800GTs ($450) are getting 37 fps (compared to 25 by the 8800ULTRA) at the resolution of 1920 x 1200 (where you really don't need anti aliasing). So basically you are paying $450 and getting nearly the same fps as a $1800 set up. (http://www.anandtech.com/video/showdoc.aspx?i=3209&p=5)

So, yes, I think the whole triple SLI thing is pretty misleading, and is really the sort of stuff that falsely scares people about PC gaming. Keep in mind those are two 8800GTs performing 5 fps behind three 8800GTX cards. Like I said, this is more of an Nvidiot issue.

edit:

I do agree that Crysis needs better performance tweaking of course. I mean Hoob was having issues as well, so there is a problem here.

Because there are a lot of PC gamers that will buy into pretty much anything.  That's why SLI exists in the first place and pretty much why companies get away with releasing poorly running games like Crysis.
