AMD is at the moment on lowest point in GPU segment compare to NVIDIA in their history.
Strongest AMD card have 32fps in Unigine 2 Superposition and strongest NVIDIA GeForce 71 fps.
That mean NVIDIA just cross point and become stronger with single high end GeForce than two high end Radeons in same time in same power consumption class, 250-260W.
Maybe AMD change situation on CPU field, but they are on same point in GPU section now.
