If the 4080 rumors of being 60% faster than a 3090 are true, that card will cost over $2000. If it comes out this year, how can it not cost over 2k? The price increases have already started to scale linearly with the performance increases even before mining came into the picture. So, 60% faster than a 3090 means at least 60% more expensive too, so around $2400-ish for the crappy models. 4090 should be at least $3000, but probably closer to $5000 because it's a halo card. I honestly think gaming enthusiasts are fine with this since they seem to be paying those prices already. 3080Ti sold out instantly in the EVGA waiting line at $1500+, and that was mostly to gamers. So a bump to $2400 seems in order. If that sells out instantly too, which it will, then the RTX 5080 will probably get bumped to $3000. Keep paying and Nvidia will keep raising.
While possible, I think given all of the economic factors happening right now and likely to affect the future means they won't be able to get those prices.
