Perhaps the fastest silent graphics card in the making, PowerColor's new HD 6850 SCS3 finally taken shape, and will launch soon. The card was spotted first in November 2010, but has since undergone many little changes, particularly with its PCB and components. The card is designed to draw power from one 6-pin power connector, and run the GPU at reference speeds, while relying entirely on a massive heatsink to cool it. The heatsink uses five copper heat pipes to draw heat directly from the GPU, and through the large aluminum fin array. The HD 6850 features 960 stream processors, and 1 GB of GDDR5 memory over a 256-bit wide memory interface.
