Have you not taken onboard that NV have started releasing drivers to improve kepler performance or are you just ignoring it while continue to peddle NV deliberately lied about the 970. 290\x & 7xxx lasted so long, as AMD didnt have anything else to sell, so had so choice to ring as much as they could out of those products.
Strange how some people complain there isnt enough GPU launches, yet when NV keep releasing better products, they get canned for not concentrating enough on previous releases...Funny.
Well, at least from my perspective, it's hard to see how NV's more-regular release schedule is so difficult to keep up with from a driver perspective. NV used to have a sterling reputation in drivers, I remember that a few years that was one of the most-compelling arguments that you could make in favor of buying NV: you could buy one and then be confident that drivers for the card, for sli, whatever, would be better than AMD or at least as good for the life of the card.
Now, there is a serious question about either NV's ability to keep their drivers up to date on the old cards, or, more nefariously, as to whether they deliberately negelected those drivers in order to encourage old customers to upgrade more often. Perhaps they just can't afford a decent driver team...but, based upon the company's behavior over the past 10+ years and the huge profits that they are making, I'd say that the preponderance of the evidence points to the latter.
That's hilarious coming from NV followers who bashed AMD's frame times with HD7000 series but AMD actually worked to fix the problem instead of closing their eyes because R9 200 series was release. I guess it's OK that R9 270X crushes 580 by 30%, that 680 can't even beat an R9 280 today and 960 OC coming close to 780Ti in some titles.

Are you saying that tom's video card comparison chart is wrong??? Oh, the humanity!
