As far as I can tell, in terms of MSRP, 980ti was $649 at launch. 1080 and 1080ti were both $699 when they hit the market.
reply$699 in 2015 (when the 1080 was new) is ~$975 today, adjusted for inflation.
$975 is pretty close to the launch MSRP of a 5080, which is "just" $999. (We can't actually buy them for $999, of course, but we couldn't usually get 1080 cards at MSRP during the mining frenzy a decade ago either.)
The big difference here is that by the time the 2080 had saturated the market, you could regularly find a 1080 for ~$300 (I paid $275 for an EVGA B-stock model).
replyWhereas today, with the 5000 series in the market for quite a while already, a 4080 is still well over MSRP
Back in the day 1080 was top of the line. For couple of generations now it's xx90 lineup.
replyYou could say that there was Titan but in practice they were not seriously considered. At least for gaming.
