Honestly cant see myself spending more than 700ish for a GPU, that being said I will happily buy used in order to still maximize performance per dollar spent as I have done for years at this point.
Though in reality I'll upgrade to suit the need, if there is a title that I must play and I know that its beyond what my 7900 XTX can support then I'll likely sell this card (if today, it would likely be at cost or even a profit strangely enough) to look at the next step up. It would be hard to see anything short of a 4090 as an upgrade. Would have to be bewitched to spend 3k on a GPU though...
That being said its all relative, I come from lets just say extremely meager means on more than one occasion so my barometer for such things is skewed in that direction.
