To all the Nvidia fans and people that think the HD 7950 is a crappy GPU:
I hope that this review is not right, otherwise outside of bitmining or OpenCL stuff there's no reason to buy midrange AMD GPUs. Maybe GCN & OpenCl will be better supported in the future, but to the layman nobody cares if it is AMD or Nvidia unless they're using CUDA acceleration and PhysX. I don't think anyone can argue that Nvidia's Kepler cards are better in terms of actual hardware. They are crippled memory bus wise, less VRAM, use more power, and they are stock clocked higher (less OCing too).
Nvidia already has CUDA, PhysX, "way it is meant to be played" titles... so this would be a GPU death of AMD unless they can get their drivers to work better.
Side note: The problem with Nvidia having higher fluidity is that AMD stock will just drop lower... which means AMD will be failing at everything.
Right now up to the $300 mark, Nvidia doesn't have a stranglehold. If they can break through to the GTX 660 Ti and GTX 660 (~HD7870 which is plagued by black screens), then AMD is in deep trouble because the only cards less than that are the GTX 650 Ti , GTX 650, and GT640 (and other crappy stuff like GT 630, GT 620, Gt 610).
