Below you can see the AMD Radeon HD 7770 inside our test system:
For today's comparison, we're using one card for single card operation and one for CrossfireX. Against the HIS Radeon HD 7750 iCooler, we're selecting the EVGA GeForce GTS 450 FTW and, to combat the dual-GPU configuration, we're running an AMD Radeon HD 6950 1GB card.

In our first test of the AMD Radeon HD 7750 we found our highest stable overlock at the limits of VECC Overdrive. We suspect there is more to come when the various third party overclocking tools are updated to support the 7750 more completely, but for now 900e/1250m is the top clock we could hit and is what is represented in the Overclocked results. In our tests we're going to seperate single and dual card results.
