Here's my current setup. 6x Sapphire 7970s on Win8x64. Slightly OC'd while also undervolted from 1.175 to 1.090
Don't mind the ghettoness, this is my first rig. I'm getting aluminum pieces this week and going to make them really nice, also getting ready for 2nd rig. This is Damn Fun

**Also I just learned low 760s are achieved with 1090/1500. I'm going to play with that for a bit and see how low I can get the voltage.
