Single-box win/mac solutions may never catch up to multi-box linux set-ups but I expect it won't be long before single-box setups run 4K effectively and Linux will start to only distinguish itself only in 4K 3D, 48/60 FPS 4K features, and some specialty higher-than-4K DI situations. Which is probably reason enough for it to live on...
I think there will be a small explosion of new hardware configs being tested in the next couple months, with new processors, GPUs, and PCI 3.0 motherboards... I'm hoping that BM is testing these and gives us some good config updates as v9.0 comes around.
