Overclocking Asus 7870 2GB DC2

[Spruce]

Hi

What's the recommended procedure of overclocking the graphics card?
Anything else that can go horribly wrong except overheating and noticing artifacts?
Any good software for testing that include 3D animations to detect artifacts?
Been think about OCCT or MSI Kombustor maybe.

Regards
