let I start out with a forward by say the card be a beast ! I upgrade from a mid-range 9800gt to this thing and get dx11 support , thrice the graphic process power , and a card that can run everything I can throw at it at 40fps or above . I do not really fancy the Dirt 3 that much , but hey , a free game be a free game . if you be into GPGPU application then this one be definitely a home-run hitter with its 2tflop compute power . mining bitcoin yield 250mh , although it falter when GPU render in Sony Vegas . however , the card be rather large . in fact , I have to rearrange some cable just to get it to fit in my case . regard actual performance ; while AMD be gain market share , the majority of game be seemingly develop for Nvidia . in fact , Deus ex Human Revolution , a game that be once often gifted with AMD card , suffer from periodic slowdown , even with this beastly card . the slowdown be not limit to this game , however , and be exacerbate by record with frap . also , the driver for AMD -lrb- namesake `` catalyst '' -rrb- be also notoriously inferior to Nvidia 's . the change be not aptly document enough , and I have yet to find how to maintain my image aspect ratio in game -lrb- all the information I find on Google be for driver at least 3 version earlier -rrb- . the molex to 6 pin adapter that come with it appear flimsy at first , you have to force the connector in a bit until it slip in . if either connector be not plug in you 'll get the fan run at jet engine speed and no display , although you usb device will be work fine . also , I would not count on that rebate . just assume it be money lose .
