The cost/performance is terrible for higher end cards. In a few years your card is now worth nothing because the lower end cards of the next gen are matching it and there's yet another new SOTA card out. So people end up buying that and chasing the dragon.
The 4k situation is a good point because nvidia deliberately don't provide 24GB except the 90 series, but ... you're too good for DLSS? You can't move a texture slider down from Ultra to Super High? It's your choice, just like it's your choice to pay for Claude. I am also allowed to think you're being stupid.
Someone who bought a 4090 "a few years" ago can now sell it for more than they paid for it, but never mind that.
