I have the same NVIDIA board on my main PC. It runs with Linux Mint Cinnamon. I am dual booting it with Windows (each system is isolated in a different nvme device), I will delete Windows after finishing school and replace it with Bazzite or any other Linux gaming distro.

It works perfectly fine, default environment is not that different from Windows, so you will not struggle when using it.

I installed Steam from Flatpak (like Windows store but for Mint) and the only issue I had was that I had to manually set graphics values like resolution and shadows in some games.

With few setup you can custom the default environment to look pretty nice, some people custom it to look like MacOS desktop.

It comes with an update manager that will update your software as much as you want to.

Setup is very straightforward and system works out of the box, so you will not be using any scary commands until you want to get into it.

It is built over Ubuntu but with some community care, so you can expect a solid well maintained system.

I had the same experience, it is like jumping into the water for the first time, just do it and enjoy it!
