Colin McRae Rally 2005

Colin McRae Rally 2005 makes extensive use of pixel shaders, whose speed directly depends on the GPU frequency. This fact explains the results the Leadtek WinFast PX6600 GT TDH SLI shows in this game. Although the SLI platform is comparable to the ATI RADEON family only in 1024x768, it is always faster than the GeForce 6800 Ultra. We also enjoyed a noticeable bonus from overclocking the Leadtek kit here: about 10%.

Despite some architectural flaws, the dual-Leadtek kit outperformed GeForce 6800 Ultra in the first two resolutions and ran neck and neck with it in 1600x1200. Anyway, the winner’s laurels remained by ATI RADEON graphics cards, which proved faster when processing pixel shaders.
