Vista worked fine for me too, except i was getting 20 less fps in games. I dont have the same system as the review or play at that high resolution monitor so maybe its a little faster than vista. But on my core2duo 9800gtx XP is way faster in games than vista, I know I got dual boot. Windows 7 doesnt seem that much faster than vista so I cant see it being faster than XP on my system anyway. Windows 7 ? Meh..
