Never know, Intel could possibly make a card like that using GDDR6. Might be closer to $375-400 but even then, that's not horrible and I wouldn't be surprised if we see something like that after Battlemage.
As far as value goes, I think it does happen but consumers really have to do their homework to find it. Something I've mentioned multiple times with the 40 series is how the 4070 Ti Super really went unnoticed by many. This card launched at $799 MSRP, and could easily be had for that including some OC models, and very few talked about it. It was merely a cutdown 4080 and I saw prices drop to $749. That's the same I paid for an Asus OC Edition 1080 Ti seven years ago but this card would run circles around it plus all the NV bells and whistles. Those days are gone now that inventory is drying up for the high-end 40 series but it was something I tracked since it was released. AMD has had its share a mid-tier cards as well in recent years that do well. On more than a few occasions, the Arc 770 dropped to ~$300 range. For mid-to-low tiers value can be found but it takes research. High-end halo stuff, nope, we're screwed.
