Sapphire Radeon HD 7790 Dual-X OC Review @ OCC
 

A high performance FPS beast the Sapphire HD 7790 is not, nor is it meant to be. That being the case the FPS performance it delivered while using upper end settings is pretty impressive, all things considered. In every test run it was faster than the target competitor's card, the GTX 650Ti, at the target price point of $149/159. While running the gaming tests I found the HD 7790 delivered smooth game play with the settings used for my tests. A tangible result when you compare apples to apples.
