I think we've topped out on how good GPUs realistically need to be. The games industry is embroiled in layoffs. AAA games as we knew them are ending because they're just not compatible with our current macroeconomic situation. My current GPU is an RX590 (released in 2018, I bought it new in 2019) and I have no plans to upgrade any time soon.
Realistically, I think that if AMD and NVIDIA both abandon the gaming market entirely (unlikely, IMO) then Intel or some Chinese no-name brand will pick up the slack. Video cards for gaming don't need to be bleeding edge any more. 99.999% of experiences gamedevs want to create don't require that horsepower, and consumers can't afford it anyway (at least not when effectively bidding for fab capacity against billionaires who are convinced they can be immortal Gods if they win the auction). Most likely, no-name chips from non-frontier fabs (or by Chinese fabs trying to claw their way upmarket) will be badge-engineered as AMD/Nvidia/Intel.
Alternatively, we have WW3 and either advanced, PC-gaming civilization ends completely, or we at least have to sacrifice consumer goods like video cards for the duration.
