For the price of a 6950, you can get yourself a working 6970.

Interested?

Follow this link and go through the instructions. It also shows you how to detect if your card has switched, how to fix it if you did something wrong and has test results from people who have tried it (at the point of me typing this, 28/28 worked).

Note: This is for the 6950, there are no bios unlocks for the 6970

Apparently some people have lower minimum framerates in games after the flash.. most likely the stupid power throttling settings are implemented partly in hardware

Very tempted tho
