XFX Radeon HD 7770 Jet Black Edition Super Overclock vs GTX 560 @ HardwareHeaven.com
 

At the top of XFX's 7770 range is the "Jet Black" version of their usual Black Edition Overclocked model with this revision featuring heavily overclocked core and memory, well in excess of the AMD reference design. Today we have one on our test bench and will be putting it up against the GTX 560, also overclocked, in a selection of real world tests including Battlefield 3 and Star Wars: The Old Republic.
