Now... You must set it on fire...
FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net
Note the warning on Burn-in Test - It will stress your card, make sure you have adequate cooling system in place or you can damage your card, especially if you are overclocking the card and haven't adjusted your card's fan settings.
As I found a person who bought a cheaper card with passive cooling (IE, just a heat sink), you don't want to push the card too much.
