PowerColor ignored the claims that there would be no dual GPU HD 7990 and created the DEVIL13, with two southern island GPUs on a single PCB. Both GPUs run at the standard HD 7970 speed of 925MHz, with a button to overclock them to 1000MHz and ups the amount of voltage provided to the cores as well, the 6GB of RAM run at the stock 5.5GHz effective. Seeing three 8pin PCIe power connectors is impressive, as is the 3 slot card its self. [H]ard|OCP overclocked the card to a stable 1125MHz GPUs and 6.3GHz memory which put its performance noticeably above that of the SLI'd GTX 680 that they compared this card to. The question remains, if you can get the exact same performance from two overclocked Powercolor HD 7970s for $860 then why spend $1000 on the hard to find DEVIL13?
"PowerColor has beaten AMD to the punch with its own creation of a dual-GPU Radeon HD 7970 CrossFireX solution in a single video card package. We evaluate this awe inspiring video card and of course overclock it to its highest potential. We put it up against the best GTX 680 SLI solution also overclocked, all with the latest drivers."
