Flashing a 6950 to be a 6970 seems really cool, but how does the computer recognize the card? Does it still think its a 6950? I ordered one recently and while I don't have the money to crossfire a second just I see it as a possibility in the future. If cards a year or two from now can not be flashed to 6970s like the current set, would you need to crossfire it to the 6950 or 6970?
You can crossfire a 6950 with a 6970 anyway so it wouldnt make a differance as far as i can see. When crossfiring usually the faster card would downclock to the same speed as the slowest. Not every time but usually. So it wouldnt really be an issue as far as im concerned.
