XFX R7790 Black Edition Overclocked Review @ OCC
 

The R7790 is not built to be a high resolution gaming power house but a good solid performer at the $150 price point. At 1920x1080 resolutions you get playable frame rates in almost all of the games tested with Metro 2033 the lone game under 30 FPS. The idea here is to offer enough performance to get the job done while keeping the price point attractive. As a competitor for the GTX 650Ti, the XFX R7790 Black Edition leads the GTX 650Ti in every test save one where the margin of performance is within a single FPS.
