Windows 7 isn’t release yet.
Most everything runs better under Win7 than Vista. I play CS:S, Left4Dead, Unreal, Battlefield, etc. all about the same on Win7 as I do under WinXP. Vista, on the other hand, is a hog.
For gaming but doesnt support direct x10 so w7 is lighter than vista which means.
For gaming but its beta now and wouldnt have beta running as your main.
and GTA 4 does not run well now?
well, windows 7 will supposedly have better resource management than vista (not 2 hard), so it will run better.
