Vista - best os for gaming

hey everyone

i have recently bought a new pc and am wandering what os is best for games such as dawn of war 2 and supreme commander...i currently have windows xp home sp2 and pc specs are below:

amd phenom 2 x4 810 (4x2.61 mhz) (type according to aida32:amd athlon 64,1800 mhz)
nvidia geforce 7025/nvidia nforce 630a or geforce 7200 gs
4 gb ddr2 ram (3.5 gb in system info)
C-Media CMI8738/C3DX Audio Device is the sound card according to aida32
500 gb sata hard drive (not sure exactly what it is)

Desolator,

I think you'll find that everyone will have a different opinion on which is best. I built a new PC recently and installed Vista Home Premium x64. My old PC has XP Pro. Seems that both work equally well for gaming to me at least. I have had no OS related problems running games with Visat x64. I would have no reason to downgrade my OS back to XP Pro.

I have Windows XP Home Edition, Windows Vista Home Premium and Windows 7 on my system, and i've found that Vista seems to be the best for gaming, with Windows 7 coming a close second, Windows XP is last, for some reason my games run slower on Windows XP compared to Vista or 7.

Hello Desolatator,
If you want to take full advantage of your 4 Gig of ram then x64 is the way to go, as x32 only uses about 3 Gig.

thanks everyone...this has been very helpful

Your welcome.

I haven't noticed any difference playing Everquest under WinXP or under Vista.
