Call of Duty 2

The gap between the GeForce 7900 GTX and the GeForce 7800 GTX 512 is getting smaller as the display resolution grows up because of the limiting effect of the graphics memory; the newer card has a slightly lower memory clock rate than the older one.

As for the multi-GPU configurations, the Radeon X1900 XT CrossFire is better in Call of Duty 2 thanks to its 96 pixel processors. The ring-bus memory controller gives the Radeon X1900 CrossFire an edge in the more resource-consuming 8x FSAA + 16x AF mode. This configuration makes the resolution of 1280x1024 playable, while the GeForce 7900 GTX SLI only allows playing the game with comfort in 1024x768. The maximum level of antialiasing is hardly available here since the two GeForce 7900 GTX deliver an average frame rate of less than 50fps in 1024x768.
