Games that support 64bit OS

Upon Windows 7 coming out I'm thinking about buying a new computer as the one that I currently have is starting to be a little dated as you can see in the System specs of my signature. What games if any currently support a 64bit OS as I would actually like to run something that is slightly more secure but yet has access to more than 3GB of ram. Any suggestions or thoughts of where I can go to find a list of games?Games that support 64bit OS
Any game can run on a 64bit OS, except very old ones, like MK 4.As for 64 bit games, there aren't many, Half Life 2, Crysis, I think L4D and TF 2 are 64bit too or at least they have a 64 bit mode, anyway these are the only ones that I know.Games that support 64bit OS
I'm running 64bit and I have yet to have any problem running any games. The oldest games that I have tried playing are probably C%26C and starcraft which worked just fine.
Old dos games from 96' and earlier won't work , but you can get an dosbox emulator to play those . Everything else works just fine .
Only one I know of is EVE. I believe they have a 64bit client ?



Win7 is supposed to offer a XP shell to run older programs. Only issue with it is you need certain processors to access this function.
