It's the exact same one I bought, but from ++++. It's pretty simple to do the shaders unlock, follow the guide on Techpowerup. I did overclock it to the 6970 clocks on stock voltage so I guess that's good. Reason I asked was I'm not sure if I'm missing out on anything from not using the 6970 bios.
So I got a Powercolor card yesterday and could only unlock the shaders to 1536. I flashed with 6970 bios and it wouldn't boot up. Is there much difference between a card with unlocked shaders vs a 6950 with 6970 bios?
