With the HD 7770 FleX coming in at 100 MHz less than the Sapphire HD 7770 Vapor X, I didn’t expect it to be the top performing HD 7770 that we have tested. It did however still best the HD 6850 ever so slightly in both performance modes, but not in extreme and high as expected. That puts the HD 7770 FleX right in with the GTX 460. Clearly this isn’t the highest card on the market, but considering the size and power usage it is a nice improvement over the HD 6850 and GTX 460 that it tested near.
