Just recently got a Sapphire HD 6670 and i seem to be getting screen artifacts after an hour of gaming, i have overclocked it to 900 mhz core clock and 1700 mhz mem clock, definitley know its not overheating as load temps never go past 55c.

Either lower the clocks or turn up the voltage; Artifacts are usually the result of an unstable overclock.
