Call of Juarez
The game doesn’t support resolutions above 1920x1200, so there are no results for 2560x1600.
It is the frequency of the GPU’s computing modules that determines a graphics card’s performance in Call of Juarez. Therefore the Sapphire enjoys the biggest advantage here: over 10% at 1920x1200.
Unfortunately, the bottom speed is too low even at 1280x1024, so none of the tested cards makes the game playable at the highest graphics quality settings. The GeForce GTX 260 looks better than the others, yet its bottom speed is below the desired 25fps, too.
Call of Duty 4: Modern Warfare
As you could expect, the pre-overclocked frequencies of the Toxic HD 4850 do not ensure any advantage over the reference card from ATI. These cards both deliver superb performance in this game, being only inferior to the Radeon HD 4870 at resolutions above 1280x1024.
