Been running tests on this card all day, getting some very odd results. First run I get almost identical scores to the Asus Direct CUII from the Guru3D review minus the Physics score due to an i5 4670K processor instead of the 3960X used by Guru3D. 10130ish Graphics Score on the base runs with no OC over stock settings. 7600ish Physics Score on the base runs with no OC over stock settings. Using 1100/1400 core/memory clocks I'm seeing: 9348 Graphics Score 8496 Physics Score This is repeatable 100% and it seems lowering memory back down to stock speeds (1250) improves the Graphics score and reduces the Physics score. Just wondering if anyone else has seen a similar loss in performance when OC'ing or has any ideas what's going tits up with this one!!!
