Call of Juarez

The overclocked Radeon HD 3870 is as fast as the GeForce 9800 GTX at resolutions above 1280x1024 (it has a lower minimum of speed, though). This is not enough to have really high results in the tech demo from Call of Juarez DX10, however. The Radeon HD 3870 X2 remains unrivalled.

Call of Duty 4: Modern Warfare

The overclocking leads to a 15% increase in speed at 1280x1024. Unfortunately, the OpenGL driver from ATI’s Catalyst suite is still imperfect. The Radeon HD 3870 is slower than its opponents even with its GPU overclocked by 30%.
