I went to bazzite with a 4070ti super, is it worth going to a 9070xt? I've had graphical issues but a reboot always fixes it. The main menu UI is dog slow though (easily a half second of lag).

I can't speak for the 9070XT specifically (I'm on a 7800XT myself), but the thing with Linux in general is that nVidia can be a PITA sometimes and exhibit weird issues like your menu lag. If you want a first-class Linux experience then go all-AMD. I run Linux on four different classes of all-AMD computers (desktop, laptop, mini-PC and handheld) and have literally zero issues. In particular, I've been running Bazzite for about three years on two of my systems (PC and laptop) and it's been rock solid. Three years of updates and upgrades, with only one hiccup this one time on my PC (which wasn't a big deal either since I had pinned a good image versions to my boot menu, so I always have a good image I could boot into).
