Well after since i bought my 9500gt pcie card, i was using XP, superior performance, so i decided to install Vista. 4.2 Score, for graphics. However, i lose about 10% performance in games, and its hard for me to record any game using fraps with decent performance. Vista and Win 7 may look nice, have some nice features, but i guess vista and win 7 is aim for the high end cards right? Guess i will be using XP home edition and XP pro for my 2 rigs(once i get the other one ) until XP is completely not being supported anymore. Btw, using Vista or win 7 is not too bad, i mean XP still seems way faster in games, etc, but losing about 20% of performance is not a good thing, but not as bad. Even Crysis warhead runs beautiful, however recording is a pain in the butt.
