Linux probably wouldn't make your games any faster, but it could make the OS feel snappier.

Reasons to switch:

• you hate Windows
• you like to customize stuff
• you're curious about Linux
• you don't play many MP games
• you tend to leave a ton of stuff open, which makes things run slowly
• saving 40GB or so of space means the world to you (Linux is pretty lean)

Reasons not to switch:

• you need Windows-specific software, like Adobe stuff or games w/ anti-cheat
• you're not interested in tinkering at all, and having any minor issue would frustrate you
• you want the best possible performance for games

Linux is better at memory and task management, generally speaking, but performance in specific apps depends a ton on the specific app, from being slightly better to being noticeable worse.

As for which Linux distro to go with, I hear good things about Linux Mint, though I don't use it myself. But honestly, look at the most popular distros and find one that looks cool to you, they're all pretty good. Ones to check out are:

• Debian (or Linux Mint Debian Edition) - ol' reliable, may have some issues on newer games
• Fedora - tries to be close to bleeding edge, without as many sharp edges
• Bazzite - gaming focus, tries to imitate Steam OS
• openSUSE Tumbleweed - my personal daily driver, though I generally don't recommend it for new users since there's not a huge community to find help

There are tons more great ones. If you list your must-have apps/games, maybe someone can give a better recommendation, though honestly most distros are similar enough that if it works on one, it'll work anywhere.
