Performance with overclockingWe wanted to observe the gains we could get with a 20% GPU overclocking on the Radeon HD 7770, followed by a 20% memory overclocking and finally with both the memory and the GPU overclocked by 20%.
We also included the results for the Radeon HD 6850.
These results were obtained at 1920x1080 at the very high quality mode:

The 20% GPU overclocking is translated into a 5 to 15% gain in games and the memory overclocking into a more modest gain of 3 to 11%.
With both the GPU and memory overclocked, we observed gains of between 16 and 20% with an average gain of 18%.
