I bought 2 5870's back in September. Awesome cards but I just learned today that disabling the Catalyst AI disables Crossfire. That really sucks, since the AI gives me plenty of issues with different games and I'd really like to play with it off. Solely because of this I'm looking to sell my 5870's and pick up a 5970 so I can have the best of both worlds. My question is about the 5970, with it having 2 GPU's on a single PCB, will my Catalyst Manager read this as a linked setup or just a single card?
