Some people are extremely anti-OCCT, but as long as you keep an eye on temps, don't have a card that was defective out of the box, and don't use stupid levels of GPU voltage, you'll probably be fine.

FurMark, just to get confirmation of stability from a second test.

Crysis GPU bench on loop, or looped 3DMark can use much more VRAM and can thus find VRAM instabilities OCCT and FurMark may overlook.
