I hear that the 6950 can unlock to a 6970 with a bios flash. Can someone please point me in the direction of the guide that outlines this please?
6950 = $300
Should I just do the bios flash and save myself $70 or should I just buy the 6970?
I hear that non-reference 6970's are coming out. Should I just hold off another few weeks and then pull the trigger?
I personally have two 6950's flashed to 6970's. Very pleased so far. However it is not guaranteed so if you are not willing to take what appears to be about a 10% chance of failure, go with your gut and budget. Performance is pretty close between both models and if you are willing to OC some, you can get a 6950 to perform on par with a stock 6970.
The non reference cards should start showing up soon, they will run cooler and quieter more than likely than the current reference based cards.
