You missed the most important areas -- where the card actually lands in terms of its code-name and its standing in the line-up. NV could take any chip it has and call it x50, x60, x70, x80. That tells us absolutely nothing. Using your logic, had NV delayed GTX460 and called it GTX480 and priced it at $499, you'd call that high-end. Same for 6600GT that smashed a 5950U or 680 that beat GTX580. Sorry, 680 and 980 are not high-end cards no matter how much you keep claiming they are. Just because NV priced them at $499-549 doesn't mean they were high-end. It's more akin to NV got away with pricing a mid-range x60 card and calling it an x80 card due to lack of competition.
Another common sense logic to this argument is never in the history of NV's generations did NV release a high-end card of the same architecture/gen only to then release a flagship card 40%+ faster. In that case, GTX780Ti is from the exact same generation as GTX680 and 680 is really a 660Ti and 780Ti is a 680. The same applies for 980 and 980Ti. 980 is really a 960Ti, nothing more nothing less.
That's not how GPU generations work. I am sorry if you started following the graphics card industry only in the last 5 years but you are wrong. Had NV split its historical GPU generations into 2 halves (bifurcated a generation), then might as well start calling GeForce 4 Ti 4200 as GeForce 4800, GeForce 5700U as GeForce 5900U, etc.
No, it's only high-end based on marketing. As 680 and 980 stand in the respective Kepler and Maxwell line-ups, these are historically speaking $250-300 mid-range chips, priced at $500-550. Price alone doesn't determine if the card is mid-range or high-end anymore after NV changed the way they market and split a generation.
Another evidence your entire post is wrong is NV has never released a next generation flagship that wasn't at least 40%+ faster than the last generation's flagship. By that account both the 680 and 980 cannot be considered true flagships, not to mention so many other metrics that already prove they are mid-range chips. Most of the forum will agree with my assessment.
By very definition of 980 being a 392mm die and GM200 being 601mm2 already proves that 980 is a mid-range and there is a flagship sitting above it with nearly 50% greater die size. You just contradicted your own post.
I know it's
very hard for some people to accept that GTX680 and 980 are mid-range chips, I guess because some of them would be admitting to getting ripped off by buying a $500-550 mid-range GTX560Ti successor. In the case of a 680 vs. 780Ti, it's far worse than 560Ti and in that Fermi generation at best would be called a GTX560. 980 is clearly a mid-range $250 GTX960Ti:
$250 GTX560Ti (980) vs. $350 GTX570 vs. $500 580 (aka 980Ti/Titan X level):

It's only high-end from a marketing perspective, not engineering perspective. If tomorrow the top 5 audiophile manufacturers doubled the prices of their headphones, that would still make Sennheiser's HD598 low-end, HD650 mid-range and HD800 High-end.
This is only valid if the videocard's names actually meant anything in 2015 - in many cases, they don't. R9 390X isn't a true x90 series card from AMD. GTX960 is in no way shape or form a true x60 series card either. The names don't mean anything anymore and to get a true understanding one needs to dive into the GPU codename (GTX960 is the 3rd chip from the top so it's decidely low-end) while R9 390X is a 2nd chip from the top so it's mid-range and should have been called R9 380X.
Secondly, you are ignoring historical generational leaps. Both the R9 390X and GTX960, along with GTX980 are faux x90, x60 and x80 series cards as none of these live up to the expectations of a true x90 AMD card, x60 NV card or x80 NV card. All of these cards are branded incorrectly -- or I suppose correctly if we are talking marketing brainwashing to the masses who buy into the marketing names.
Sorry to break it to you but in BMW's stack 2-4 series is low-end, 5 series
is mid-range and 6-7 series is high-end. Honda Accord is less luxurious than a compact/entry-level luxury sedans (i.e., 3 series, Audi A4, C-Class) so it's below low-end luxury segment. This is the same mistake you are making when comparing videocards -- you aren't comparing the product segmentation in the entire product line-up vs. the entire market. Honda Accord is a low-end car because essentially it's just barely a class above a Honda Civic/Mazda 3/Ford Focus with the primary differentiator being size, not much more luxury. Even if they made the Accord the size of the S-Class/7 Series, it would still be below the Audi A4/C-Class status because a car's size alone doesn't determine its luxury status.
Anyway, not sure what this has to do with Pascal's mid-range successor trouncing GTX980Ti other than you are really really trying to call that GP204 card High-end? I think you should really do some reading on NV's GPU generations going back to GeForce 2 before you provide any reasonable rebuttal. I suggest you start here and start matching next gen mid-range vs. last gen flagship to see what actually happens:

Now, since NV already got away with pricing its next generation mid-range chips/card at flagship prices with GTX680 and 980, it's a virtual guarantee that as long as the GP204 Pascal chip is even 5-15% faster than 980Ti, NV will slap a $500-550 price on it and market the hell out of it as an x80 series Pascal card. NV's new GPU strategy is 100% bullet-proof and I hope the top management in their marketing department is getting awesome bonuses.
I still remember certain posters defending GTX980 for the last 9 months, constantly claiming that it wasn't worth waiting for NV's/AMD's true flagship to launch. Boy, now a $680 MSI Gaming 6 980Ti is
49% faster than a reference $550 980 at 4K:
I guess it's really hard for some people to accept they got ripped off buying a mid-range GM204 chip for $550 even when the evidence is staring in their face since the 980Ti dropped. Historically speaking, there should never be a perfectly linear price/performance relationship between a mid-range and a flagship card which means a 980 today should cost well below $450 because there is a certain premium/bragging rights attached to the 980Ti.
