Looking to spend between $300 to $800 max for a gpu that will run ai models efficiently. The 1080 TI has 11 GB of ram, but no tensor cores, so it seems like not the best choice.

Just got a new rig, with a 3080 super, which I thought would be good, but it only has 8 GB of ram, big bummer, so I want to replace it with something that will do a better job. What should I get?
