I updated my earlier post to that already.
It's actually surprising that the gtx 780 ti still has the performance per watt advantage. But keplar aged badly for sure, but this is because Nvidia is happy to see keplar fail because most people who bought a maxwell were likely keplar owners or older. But upon release, the gtx 780 ti had a big performance per watt advantage. It consumed alot less power than a 290x and performed better.
This changed when nvidia released maxwell, because kepler was no longer a priority. And giving boosts to maxwell, while adding taking away performance away from Kepler was their number 1 priority.
Keplar had such a high install base that, that it staying strong in reviews and benchmarks meant less people upgrading. The only way for people to upgrade from it, was to see it fail. As said in my earlier post, this was the result of employing a feature that killed kepler cards(global illumination) and Nvidia being a dick and not giving optimizations for their cards to make keplar look worse than it should have done.
Games where kepler cards sucked, were ones that employed global illumination like sleeping dogs, hitman absolution and dirt rally. These were games where a 280x was competitive with a gtx 780 before maxwells launch. After maxwell was released, Nvidia didn't block this feature, kind of like async compute, and encouraged developers to use it. Thus all games started using it and this was the beginning of kepler degradation into what it is today. Since most games use this feature now, Nvidia cards have taken a tremendous hit.
