New and used GPU prices are still high. Right as prices started to dip close to reasonable levels all the 4090s started getting snapped up drying up the high end of the market. And with the horribly overinflated MSRP of mid range cards they've stayed high instead of dropping to a level that's actually reasonable for their performance. It's trickle down economics, but in the worst way possible for the consumer.
It is unfortunate but amd is just not competitive at the top tier of GPUs. You can make the argument that AMD cards are good enough, but DLSS is just magic that AMD cannot touch.
