Sapphire HD 7950 Vapor-X 3 GB @ techPowerUp
 

Sapphire's new HD 7950 Vapor-X comes overclocked out of the box. Thanks to clever use of the dual BIOS feature you can also activate a second "Lethal Boost" BIOS which runs even higher clocks. Cooling is provided by a large dual fan vapor chamber cooler which keeps the card cool and provides low noise operation.
