Can Win7 Ultimate 32bit runs HD GAMES?

[Alcom21]

Not a PRO in computers. Does Windows 7 Ultimate run's games like Crysis,Modern Warfare 2,Dead Rising 2,Gears of War 3..etc.etc...

And what is better in WINDOWS 7 ?

Let say I use Windows 7 + HD 4850. Can i play games smoothly?

32 Bit vs 64 Bit choice is more dependent on amount of memory, under 4 gigs of ram, 32 bit . If you have 4 gigs, toss up but favor 64 bit.. Must use 64 bit if more than 4 gigs.

Games like Crysis are more dependent on GPU. Check out the link below.
