6950 Crossfire Unlocking Question

post #1 of 3
Thread Starter 
I have these cards in Crossfire:

http://www.newegg.com/Product/Product.aspx?Item=N82E16814102928

Now I know for a fact I can unlock the first one to a 6970, the Dirt 3 edition had the 6970 BIOS already on it, select-able with the BIOS switch. The second one, however, has no BIOS switch, and from what little research I've done, can't be unlocked. On to my question: would it be useful to unlock the Dirt 3 in this Crossfire setup? I already have both cards running at 880/1375.

I'm not a 100% sure but I thought it is possible to just CF a 6950 w/ a 6970 so I guess this will be fine.

It's possible, sure, but what will it do to performance?
