Hey what should I upgrade my 1060 6GB with

It's been 8 years since I bought it and it still runs like a champ but ideally I'd like to actually utilize the 4k portion of my monitors.

Ideally I'd like to hit at least 16GB of VRAM since I'm of the opinion that if I'm gonna spend more than $500 on a graphics card, it better at least last the next decade of new releases gaming wise. My motherboard can probably stand an upgrade too since I have a bunch of unused USB-C ports due to the fact that the B550-F doesn't have any 3.1 headers.

Don't really have a budget but I'm posting this in the hopes someone will tell me "don't buy the 4080 super you idiot" and inform me of a better, cheaper, alternative
