do what control
I am using the Radeon9600.
it is a =n excellent card that you can control.
Lab testing see tomshardware(websit) they both the same but the 9600 you can control the settings so it will work harder.
I am playing some game and I configure the computer to have a profie for each game, and I pushed the card the results are very good.
Also with the 9600 if you spend some more money you can get some good games
Have fun
