So, how much RAM should I have if I want to game on Windows 7 64-bit? I'm currently running 2GB (previously four until one of the sticks in my other dual channel kit crapped out on me). I could boost it to six by adding the remaining working stick (if you can do that in DC mode...have two sticks running in DC, one in one of the other slots), or I COULD buy more if I needed to, but I'd rather avoid it. To be fair I'm also running a 9600GT and have no desire to upgrade my card just yet (I think I'd need a new PSU as well), so I'm not talking about power gaming...I just want things to run as smooth as they would on XP both in game and just in the OS.
