According to the website on (Geeks3D): 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.

It sure is an intensive benchmark. I use it for cards starting from the 2003-era and upwards. Because it's a very heavy benchmark it's good compare older cards with cards of a newer generation.

I used version 1.8 on 1280x1024 as shown in the screenshot:
