AMD has had the ride of a lifetime with the Radeon HD 5970, even today the dual-GPU 5-series card is still able to keep it's own against an onslaught of next-generation GPU technologies from not only themselves, but NVIDIA.
Enter, Radeon HD 6990. The GPU is a very power-hungry card crunching down on some serious 375W-TDP goodness but with its new vapor-chamber cooling system it also supports up to a get this, 450W of bench-pressing power! The card is mainly what was leaked a few weeks ago now, 2 x 1536 stream processors, 2 x 96 Texture Units, 2 x 32 ROPs, 830MHz core clock, 1.25GHz (5.0GHz data rate) GDDR5 memory, 2 x 256-bit memory bus, 2x2GB memory, and the best bit? A whopping 2 x 2.64B transitors... all packed neatly into a 40nm-process and with a price of $699.
