Call of Juarez
The game’s build-in benchmarking tools do not support a display resolution of 2560x1600, so we had to limit our test to 1920x1200.
As we already know, you can achieve a playable speed in Call of Juarez at the maximum level of detail and with enabled 4x FSAA only if you have a dual-processor solution such as Nvidia GeForce 9800 GX2 or ATI Radeon HD 3870 X2.
The GeForce 9800 GTX is over 15% ahead of the GeForce 8800 GTS 512MB at high resolutions, but this has no practical meaning because the speed only grows from 16 to 19fps.
Call of Duty 4: Modern Warfare
The performance growth is more substantial here: about 18% at 1280x1024. It helps the GeForce 9800 GTX yield a frame rate of 60fps which is the desired minimum for a first-person shooter. The gap from the GeForce 8800 GTS 512MB is smaller at the higher resolutions, varying from 11 to 13% depending on the display resolution. Both cards provide the same level of playing comfort.
