Nvidia drivers and gaming compatibility have grown leaps in the last year. I'm using dual monitors on a 2070m in a laptop, one of the historically most incompatible setups. I am running cachyos. I was able to simply install the OS and start playing my entire steam library, all without any modification. I play plenty of modern games. I don't have any AAA FPS with anticheat though, which I hear don't work at all.

Been playing everyday for about two years with my 3060ti without much issue. There's still the odd hiccup on occasion, but it's usually solved by picking a different Proton version. Most games "just work," generally without any changes.

The nVidia drivers haven't been "a mess" for quite a long time, so if that's what is holding you back, I think you'll be pleasantly surprised. ProtonDB has a massive and growing list of games that run on Linux, and you can see what people did (if anything) to get those games working.

I will caution you, however, that if any amount of tinkering makes you inwardly cringe, you might want to think twice. Linux is generally easy to use, and it's only getting easier, but there will be times you'll have to add Launch Options to a Steam game, install a mod differently, or use the command line to do something.

I got a 3060 which works fine i guess the 3080 should too

Nvidia works fine on Linux. I have an nvidia card at home, and I support a bunch of them at work. It's easy. https://docs.nvidia.com/datacenter/tesla/driver-installation-guide/latest/index.html

Use the network installation to add the deb or rpm repo, then choose whether you want the open or proprietary drivers. Install the package and that's it, your package manager will handle the dependencies.

You may need to create and enroll a dkms key if you have secureboot enabled and you haven't done that already, but that's the only wrinkle.
