IMHO the 560ti is the only Nvidia right now that offers Price/Performance Radeon has got every other place covered however if it was still the 69xx only it would be a different story but the 7950 at worst competes with the GTX 580 and cost less. Nvidia really has nothing to offer today and the drivers are great with AMD
The public is not agreeing with ya or THG. My guess is they do a little more reading and get a consensus of opinions before buying. This is what DX11 cards are hitting steam servers as of the end of February.
NVIDIA GeForce GTX 560 ----- 10.25% (Grew 0.78% last month)
NVIDIA GeForce GTX 570 ----- 4.37% (Grew 0.35% last month)
ATI Radeon HD 6950 ----- 3.83% (Shrank 0.25% last month)
NVIDIA GeForce GTX 580 ----- 3.76% (Grew 0.07% last month)
ATI Radeon HD 6970 ----- 1.85% (Grew 0.06% last month)
NVIDIA GeForce GTX 550 ----- 3.02% (Grew 0.13% last month)
In the gaming community at least, by next month given the current rate of adoption, the 560 should show twice as many cards out there than both 69xx series cards combined.
But I'll agree with ya in the below $200 segment, there's not an nVidia card I would by ..... nor would I buy the top 2 cards from either company as two mid range cards in SL / CF trounce the top two for a lot less money. Why spend $450 for a 580 when I can get 40% more performance outta two 560 Ti's for $440 ? Why spend $900 for two 580's when they only get 10% more performance than the two 560 Ti's for $440 ?
The factory OC'd 900 Mhz versions at the same price as the reference cards just have no equal .... beating the factory OC'd 6950's in CF by over 100 fps...and even beating the 6970's 37 fps. That's why they own 10+% of the market at this point.
The 570 and 6970 are a wash in single card configs (526 vs 524 fps in Guru3D game test suite) tho the 570 has a clear edge in SLI over the CF'd 6970's (873 to 825). The 580 still slightly edges the 7950 (616 to 603 fps) in single card config,.... AMD drivers need some tweaking before they can complete the test suite in CF but that will be sorted shortly I presume.
The 7950 at 603 fps in Guru3D's game test suite @ $0.80 per frame gets toasted by the following less costly choices:
Two factory OC'd 560 Ti's in SLI at 862 fps and $0.50 per frame
Two factory OC'd 6950's in CF at 759 fps and $0.63 per frame
Two factory OC'd 6870's in CF at 701 fps and $0.46 per frame
Two factory OC'd 6850's in CF at 634 fps and $0.44 per frame
NVidia is to AMD in GFX what Intel is to AMD in CPU's. AMD has the lower end of the market sewed up, Intel owns the top end. AMD had the below $200 market sewed up, nVidia wins or ties on all fronts above $200 in the 5xx versus 6xx series. What happens in the 7xxx versus 6xx remains to be seen, all we have is this:

And only time will tell how it plays out.
