I'm running Unigine at 1080p, with all the settings jacked up to the MAX but with 3D disabled.
What happens is that the benchmark starts off at about 25FPS, then shoots to 100, then ranges from 30 - 40, then after a while goes to 85 FPS, then back to 40ish. It's very bizarre.
My HD 6950's are both reference MSI boards and seem to unlock and OC just fine. Unlocking the HD 6970 shaders and overclocking to 6970 speeds didn't help much. Bumping the "power control settings" in AMD overdrive didn't help either.
System:
Intel i5 2500K (stock speed)
Corsair Force GT 3 120GB SSD
Gigabyte GA-Z68X-UD4
8GB Corsair Vengeance 1866MHz 9-10-9-27 @ 1.5V (always worked fine with GTX 570's)
XFX 750 Watt Black Edition PSU (also not the problem, since it managed to feed a pair of obscenely overclocked GTX 470's just fine)
GPU-Z says both cards are running at 8x PCI-E speeds.
Some time ago I had GTX 470's in SLI then GTX 570's in SLI. Both set ups scored better because of more consistent frame rates.
Not sure what I did wrong.
