Nvidia GPUs age fine, AMD GPUs simply "aged" better because AMD had tons of untapped potential that took them YEARS of diver updates to actually use.
Take the 7970. It can tango with a 780 at times now, were as it was right on the edge of a 680 at launch. Now imagine if AMD had actually unscrewed their driver before then, and curb stomped the 680 back in 2012, instead of waiting until now to use their card at its full potential.
So the real question is, do you want the performance you bought now, or three years from now? Most of us vote now, not three years later.
And while everyone says nvidia is gimping, that would indicate that performance is dropping. It hasnt. My 770s are no slower today then they were when maxwell came out, and STILL play everything on the market with no issues outside of forza 6. people act like nvidia is destroying their older cards, when that is simply not the case. Nvidia simply stops optimizing for cards they no longer sell. AMD did the exact same thing, but worse. They just stopped driver support altogether for their old arch, something nvidia did not do (RIP 6000 series, while the 500 series from the same era are still getting updates). The only reason AMD still optimizes for GCN 1 is that they still sell GCN 1, and will for at least another year, since the mobile 400 series has plenty of rebrands left in it.
dont act like AMD is some driver god. They are not. They update because they didnt have a full line of new GPUs to sell, not because they are some benevolent company. The moment they have a full GPU line that isnt GCN based, optimizations for GCN will disappear.
If AMD makes it to that point without going bankrupt, of course.
