And yes, this all started with the 7970 for $549 whoch got beaten by a faster and cheaper GTX680 2 1/2 months later.
If I remember correctly 7970 offered better perf/$ than the high-end offering from nv - gtx580. It also had more vram and most importantly better perf/W.
We had much pricier GPUs before 7970. Not so long ago, GTX280 much?
Its almost granted that a card released later will undercut the competition in some way. There are some exceptions, mostly on nv side (titanz is the biggest offender)
Going by your twisted logic:
NV can't compete with amd on double precision, and is yet to release something that can. Don't think maxwell with change a thing in that respect.
NV needed almost 1,5 years to match 7970 vram capacities.
NV needed 8 months to to offer perf/watt of hd7750.
NV is yet to integrate dedicated sound processing unit into their gpus.
etc, etc.
Goal shifting is pointless
