No, it gives a boost.

The 6970 bios flash has the effect of unlocking the additional shaders, overclocking the GPU and VRAM, and boosting the voltage. It's that last part that can potentially damage your card (some can handle it, some can't - you can't know until you've found out the hard way).

The bios I use is my own stock bios, but with a single line of hexadecimal modified to unlock the additional shaders that have been artificially disabled. There's also a few modded version out there that unlock the overclock limits too, so you can go higher than the normal 6950 cap, but without being forced to increase the voltage if you don't want to (though lower voltage means less overclocking ability obviously).
