Yea, originally had vista and then downgraded to xpto speed up my slow pc. Then I decided to get win 7 ultimate x32 and so far so good. The layout of the new taskbar definitely makes things easier and performance wise seems to be a bit slower then xp but much better then vista.
If you decide to go to windows 7, i recommend at least 2 gb of ram to be stable enough to play games w/o pc lag but if u are a extreme pc gamer, 4 gb is a must so background processes wont interfere.
Above I'm a proud Gran Turismo fan, not a Sony fanboy, and now a proud 360 owner, but sharing xbox live accts ATM
End of 2009 Predictions (made Jan 1, 2009): My predictions were pretty accurate, the 360 was over and the Wii was just under.
Wii: 65 mil (yea I'm crazy) 360: 35 mil (its getting there) PS3: 30 mil (the slim better do well)
End of 2010 Predictions (made Jan 7, 2010):
Wii: 81 mil 360: 47 mil PS3: 45 mil
