My brother accidently bought a 9600 SE from best buy, and that thing is absolute garbage crap monkey ass.
I'ts more than fine for Counterstrike, but I could square he was getting better performance out of his geforce4 4200.
Definately go with a radeon 9600 pro, 9600xt, 9800, or 9800 pro, depending on your budget. The 9800 pro absolutely OWNS (he bought that after getting rid of that garbage 9600 SE after a few hours). Also, even a 9700 pro couldn't hurt, though its not a dx9 card.
definately go with a 9800 pro if you can afford it
