PowerColor HD7970 Overclocking & Eyefinity Review

3D Mark Vantage

If the stock result was impressive, then when overclocked the HD7970 reveals even higher levels of performance and responds very well. 3500 improvement in P-Score is pretty good going, but the fact we see the same increase in the Extreme test is very eye-opening.

Once again showing what an enormous step up the Tahiti GPU is over the previous generation, the PowerColor when overclocked is capable of keeping up with the HD6990. Damn impressive.
