FurMark is a very intensive OpenGL benchmark that uses fur rendering
algorithms to measure the performance of the graphics card. Fur
rendering is especially adapted to overheat the GPU and that’s why
FurMark is also a perfect stability and stress test tool (also called
GPU burner) for the graphics card.
The benchmark was rendered in fullscreen mode at a resolution of 1920 x 1200 with no AA enabled on the video cards.
Benchmark Results: Neither CrossFire nor SLI systems
scale, so this benchmark is really only good for looking at the single
GPU cards. The ATI Radeon HD 5750 was able to perform 4FPS better than the GeForce GTS 250 OC, but was 12FPS behind the Radeon HD 5770.
