I have an a 6950 2GB Dirt 3 card. The one I got was an Antilies, wich does not unlock. I ordered another one today and was wondering if it is a Cayman and I can unlock it, Could I still crossfire the cards? One having more shaders than the other. I also can send back my Antilies and hope to get a cayman. So basically I am wondering if an unlocked 6950 and a non unlocked 6950 can be crossfired.
