I'm trying to finish my new build and I have the biggest of confusions with the GPU. I want to know firsthand what or how has AMD improved all his linux and incompatibility problems over the last years, or at least a reason why I should get a HD7970 over a GTX680 that's not price or marginally better performance. How's everyday gaming? Does it have problems with every other game like before? Can you Linux normally on them? How's the compatibility with Hackingtosh or Virtual Machines?
