I mean, I upgraded from a GTX 1080 Ti to a GTX 4080 last summer, and the difference in graphical quality I can get in games is pretty great. That was a multi-generation upgrade, but, when exactly do you think that GPU performance per dollar flat-lined?
1080 Ti -> 2080: 10% faster for same MSRP
2080 -> 3080: ~70% faster for the same MSRP
3080 -> 4080: 50% faster, but $700 vs. $1200 is *more than 50% more expensive*
4080 -> 5080: 10% faster, but $1200 (or $1000 for 4080 Super) vs. $1400-1700 is again more than 10% more money.
So yes your 1080 Ti -> 4080 is a huge leap, but there's basically just 2 reasons why: 1) the price also took a huge leap, and 2) the 20xx -> 30xx series was actually a generational leap, which unfortunately is an outlier as the 20xx series, 40xx series, and 50xx series all were steaming piles of generational shit. Well I guess to be fair to the 20xx, it did at least manage to not regress $/performance like the 40xx and 50xx series did. Barely.
