FurMark

FurMark is a very intensive OpenGL benchmark for the graphics card. The benchmark offers several options allowing the user to tweak the rendering: fullscreen / windowed mode, MSAA selection, window size, duration.

Increased graphics workload / power draw of FurMark 1.8.0 for all new graphics monsters such as HD 5870, HD 5970 or new GTX 480, leads to less FPS and lower scores compared to FurMark 1.7.0, source oZone3D.net / geeks3D.com
