One thing you should seriously consider looking into, is that PSU of yours .. OEM is ToPower, whilst not exactly in the same bracket as HuntKey ( garbage, pure and simple ) it isn't much better really .. I'm surprised you don't have more issues with things, seeing as the HD6950 draws about 17A @ 12v and that unit outputs 22A MAX or around 18A nominal. You really are pushing that unit into the red-line of it's ouputs, and that may cause issues later on down the line, in light of the quality of the unit ..
