To test these graphics cards, we put them in a gaming-class system which consists of an Intel Core i5 3570K processor overclocked to 4.2GHz, 8GB of 2133MHz memory from Patriot, and a solid state drive.

We used the latest, non-beta – AMD Catalyst 13.1 – drivers as we encountered some undesirable stability issues when testing with the 13.2 Beta 7 drivers.

All cards use the same test system and software configuration, making the results accurate and directly comparable.
