Sporting a custom heatsink that promises lower temperatures and noise, the PowerColor PCS++ 6950 has a very special trick up its sleeve to cap off some amazing performance potential: a dual BIOS. But not just any plain old dual BIOS. This card has a second BIOS that unlocks streamprocessors and boosts the clock speeds, essentially giving us a Radeon 6970 at a far cheaper price.
