Buy 7970s.
Buy lots of them.
Or, at least the two that board will fit.
Crossfire or not for gaming, doesn't matter. I'm not sure if it interferes with compute - SLI used to, but I don't know anything about Crossfire since I don't connect multiple cards together for gaming. And you'll want around 1000W to be comfortable. You could get away with less with two 7970s, but there's not a big cost savings, and efficiency often drops on power supplies as you get close to 100% load on them.
