ATI Radeon X1900 XTX And CrossFire: R580 Is Here
Doom 3 v1.3
By now you all know that Doom 3 performance has been a strong point for NVIDIA ever since the game was originally released. Today, NVIDIA still holds onto the overall lead in performance for this game, but only because we tested 512MB GeForce 7800 GTXs alongside their 256MB counterparts. The 512MB GeForce 7800 GTXs were about 10% and 25% faster than the Radeon X1900 XTX or X1900 CrossFire. But the 512MB GeForce 7800 GTX is also nearly impossible for end-users to get ahold of at the moment. Remove it from the equation, and the X1900 pulls ahead of the 256MB GeForce 7800 GTX by a few percentage points when anti-aliasing and anisotropic filtering are used.
