I think gitui deserves to be on the list

PFPs are bloat

Endeavor allows you to pick from a number of DEs/WMs on installationa

I guess you could try an immutable distro (Fedora Silverblue comes to mind) if you want something that just works and you don't want to use it for programming

That really doesn't sound right, I have a 930m and it ran GTA V on med-high 720p (on Windows though…), the game itself is ps3/x360 era so you probably have a problem with the driver or maybe double check it's running on dGPU

Imo it's better that you wait, you could try installing vanilla Arch in a vm and distrohop once you're ready, if PopOS is suiting all your needs imo there's no reason to get Arch on bare metal (A vm for fun and learning would be satisfying ig), on a side note, getting the proprietary NVIDIA driver to run is very simple in vanilla Arch (like a 4 steps or so)

Sektor?

It doesn't always go well, especially with beginners, I've tried Plasma on Ubuntu and decided to go back to gnome, spent whole lot of time trying to purge all the Plasma bloat but couldn't
