Call of Duty 2 was tested with a custom multi-player demo. Quality Settings were set to max, DX9 rendering, and Trilinear filtering. Optimize for SLI was enabled for all cards.
At 1024×768 X1900 CrossFire tops performance but in our testing the 7800GTX 512 SLI solution scales better with each step in resolution. Single card performance is still fastest on the 7800GTX 512 but the new X1900 cards are within striking distance where a driver update could easily make up the difference here.
