I was thinking of temple OS

Is this a troll post, or did you get trolled?

Mint is what i run on my main, as it's excellent as a daily driver. Been doing that for over 10 years now. On my other more specialized machines I run other distros more suited to the function.

Mint is pretty hassle free to set up for gaming, really. Once you have your GPU driver installed, just:
sudo apt-get update && sudo apt-get install steam

Try it and see how it goes.

I ran mint for a long time on my main rig. It's solid and will do most everything you need to. My machine is similar in spec to yours so you shouldn't have any issues. I only recently switched to OpenSUSE Tumbleweed as i wanted to try something more bleeding edge but boy do I miss Cinnamon.

I recently went mint on my laptop for the first time in years, and it's been great.

That being said, I'm now looking at switching to endeavoros instead to give me more desktop environment options. Maybe check that out?

Manjaro is my current flavour of Linux, but been gaming on Linux for over the last 2 decades on a few dustros. The technology changed alot since then and Steam's proton was the massive game changer. though now I am in the process of moving away from steam but still use proton via other game launches. Trying out lutris currently.

A little tip for running steam games: Proton is all that's required to run most steam games that aren't linux native, but adding "gamemoderun %command%" to launch options can make games run better/at all so definitely make sure you've got that set up properly (I think Mint ships with it)

Try partitioning and dual-booting to see if it'll run everything you need.
