Would be a boon to Linux gaming if AMD was interested. If AMD improved their drivers to parity with Windows, added Mantle, and Mantle was really close to as "bare metal" as we all are hoping. Kaveri would be a good fit. Kaveri + a similarly powered graphics card in AMD Dual Graphics mode would be even more so. I am very pessimistic of any of that happening, unless the Steam boxes have proven to the market they have a place, I don't think AMD will risk resources until then.
