You are off once again. The math proves your statement is false.
HD7970 OC vs. HD6970.
HD7970 @ 1180mhz is on average
72% faster than HD6970 at 1200P and
79% faster at 1600P.
HD6970 = $369
HD7970 = $549 (+49%)
HD7970 @ 1180mhz is on average 49% faster than GTX580 at 1200P and 59% faster than GTX580 at 1600P.

For overclockers, HD7970 delivered a lot more performance for each % increase in price compared to either HD6970 or GTX580 - exact opposite of what you are saying.
You are saying 49-59% increase over 1.5GB GTX580 for a $100 price increase and 72-79% over HD6970 for a $180 increase is "evolutionary"? No offense, but how can you say that? The Titan is asking $590-600 more for a 45% increase over HD7970GE! HD7970 OC is trading blows with HD6990 and you call that "evolutionary"?
vs.
Titan max OC is about 45% faster than HD7970GE stock and I am being generous as Computerbase has it at
36-38%.
HD7970GE = $410
Titan = $1000 (+144%)
Therefore, AMD by far delivered the most value increase this generation since even at $550, HD7970 OC remained the fastest single GPU on average from January 2012 to the day the Titan was released in the hands of enthusiasts/overclockers.
You continue to talk about HD7970 being priced 50% higher than HD6970 but keep missing the point that it was just $100 higher than GTX580. If you are going keep talking about how HD7970 was crazy overpriced, why didn't say a word about GTX580 being the biggest rip-off for 1 year when HD6950 @ $299 unlocked gave 90% of the performance for $200 less? You realize GTX580 cost $499 and it was just 15% faster than HD6950 unlocked for a 67% price premium? You constantly keep bringing up HD7970's launch price but always ignore that it remained the fastest single GPU for enthusiasts until the Titan launched. Did you forget what happened to GTX280/480/580? Those cards couldn't even retain performance leadership for more than a year and their prices plummeted.
1) GTX280 lost $400 of value in less than 12 months since HD4890 was $259.
2) GTX480 lost $300 of value in less than 18 months since it was going on Newegg for $175-225.
3) GTX580 lost $250 of value in less than 18 months since HD7850 OC delivered similar performance for $250.
NV still has nothing faster than HD7970 OC besides a $1000 GTX690/Titan 1.5 years later and HD7970 still sells for $390 in retail. That's better than GTX280/480/580 ever did in performance or resale value. I am not defending HD7970's price but you are slamming it so hard but said nothing of the sort for GTX280/480/580/Titan. All those cards are far worse offenders than 7970 - and none of them can make even $1 bitcoin mining.
Because JHH said in the interview that the reason they have been working on GeForce Experience is because based on their focus group testing / NV customer feedback, 80% of their customers didn't know how to tweak graphical settings or understood what in-game GPU settings mean / how they impact performance. This was during GTX690 launch unveil I believe.
