Don't know about 'recently', but I bought a new PC about 2 years ago with a 4070 super, spent about one and a half days trying to get Ubuntu to properly set up drivers, and ended up installing windows instead.

(Due to ongoing enshittification I am considering giving it another go with mint)

It's a mixed bag, most of the time the desktop cards work fine, but mobile gpus are a little more wonky. Had a desktop rtx 2070 super under endeavoros as well until the last 6 months (even on the sway community edition, which is wayland based), but I have to admit the rx 9070xt that replaced it was much easier to setup and get going with no fuss thus far (plus really easy to undervolt, so I don't use a ton of power as well).

I had a similar setup (Endeavour OS + 3080). While most daily tasks worked fine I had some large annoyances.

• Monitor Sleep would sometimes prevent VRR from working afterwards
• Actual sleep would sometimes force me to reconnect my second monitor.
• Hybernation was completely broken
• VRAM swapping does not work at all, leading to stuttering instead of simply degraded performance.

I am sure I missed some more minor ones, but there were the main reasons I got an AMD card

I believe I have the same GPU but the Ti version (I might be mistaken but it's definitely 30xx ti) and I couldn't get it to work on mint smoothly myself. Put my 7600 back in. Idk if it's the distro or not. Followed instructions online and nothing worked. Maybe I was simply missing something simple but whatever the fix is isn't intuitive for me.

Just to note: that I've only been using Linux for about a year now and have been learning as I go. I'm not a CS student or anything. Just a dude without a diploma working a blue collar job.
