XFX Radeon HD 5970 Black Edition Limited 4GB in CrossFire X Review

Overclocking today is handled by the latest version of Afterburner and both cards recorded exactly the same overclock of 905mhz on the core and 1290mhz on the memory (from 805 core/1200 memory). This is a very nice clock increase, especially when considering the cards are already supplied in an overclocked state.

We then retested our overclock with a few of the game engines.

The clock increases helped the cards generate another 3-4 fps over the ‘out of the box settings' in Crysis Warhead. Next we will try Metro 2033.

With the clocks set in our manual overclocked state, Metro 2033 was pushed by another 2 fps in both minimum and average zones. Lastly we had a rerun of Colin McRae Dirt 2.

Dirt performance was increased by around 4 frame per second at 5760×1080 which wasn't noticeable at all under real world conditions.
