Call of Juarez
The game doesn’t support resolutions above 1920x1200, so there are no results for 2560x1600.
The overclocking is more rewarding in this game, resulting in a 10% increase in average speed at a resolution of 2560x1600. The bottom speed grew by only 1fps, though. Anyway, the Radeon HD 4870 X2 is still the only graphics card that can provide a playable frame rate in Call of Juarez at the highest graphics quality settings.
Call of Duty 4: Modern Warfare
There is a 5% performance gain due to overclocking at 2560x1600. This has no effect on the gamer’s experience, yet we can see that the overclocked Radeon equals the GeForce GTX 280. Nvidia’s solution is preferable in terms of power consumption even though it is inferior to the two RV770 cores equipped with GDDR5 memory at the lower resolutions.
