Performance Mainstream Graphics Update
 

Where things get interesting is when you take anti-aliasing into account because, as I’m sure you know, the current Radeons don’t perform as well when anti-aliasing is enabled. When AA is disabled, the 3870 is actually faster than the 9600 GT, while the 3850 is almost in a dead heat with Nvidia’s newest mid-range card. When AA is enabled though, the 3870 and 3850 are around eight and 13 percent slower than the GeForce 9600 GT.
