What type of video card shoould I get for my 2gb-ram 141gb-harddiskspace 3.5ghz windows vista pc? (Iwant speed?

What ever you do don't go with a 8600gt. Like the kidneypall said. 8800gt is the best performance/speed/price ratio for video cards out right now. Its a 100 bucks and you can play just about any game at high settings even Crysis.
