You can force crossfire to work on that board, but you have to use Google for the answer. I believe it involves hacked motherboard driver. Those threads would be pretty old by now so it's going to take you a lot of searching.
Hacked mobo drivers, this doesnt sound like it will end well
I dont think given my situation, the solution is to go spend 400 dollars on a bunch of new parts. My computer runs great, even one 6870 can play new games fairly decently, and my windows rating is 7.1.
Thank you for the links. I think i may try the hacked drivers route, or a new mobo. Everything just seems unappealing, and i only have 400 to work with after i return both cards meaning im out a gaming computer for awhile.
