Give AMD some credit too. They launched the 7970 10 weeks ahead of the GTX 680 for $550 and was 10% slower out of the gate. Had the 7970 been more in line with 6970 prices ($379-399) OR had much better drivers, GTX 670/680 would have been cheaper and/or not well received.
I already gave AMD credit. Because they are non-competitive, prices continue to rise, not just stagnate.
If AMD is non competitive with Vega, we can expect reference "Founder's Edition" 1080Ti for $999, while the "MSRP" custom 1080Ti to be $899 or something insane.
