Which Linux Distro Should I Choose for Graphic Design and Gaming?

If you're serious about gaming, look into BigLinux. It comes pre-loaded with Steam and Nvidia drivers, which can save you some setup time. Plus, it allows you to game smoothly on Linux, especially with your GTX 1660 SUPER. Just make sure to check the compatibility of the games you play with Linux, especially the ones with anti-cheat systems.

I totally get your struggle with Adobe tools. Have you tried alternatives like GIMP or DaVinci Resolve? They work pretty well on Linux, but I know it takes time to get used to new software. For your gaming needs, Mint or POP OS could be better choices since they have good support and communities. You might also want to consider how comfortable you'll be switching from Windows to Linux in the long run.

Since you're coming from Windows and want to keep using some of your Adobe tools and games, maybe start with a user-friendly distribution like Mint. It has a nice interface that's similar to what you're used to, and it's pretty stable too. You'll also find that Mint supports Steam out of the box, which could help with your gaming needs while you gradually explore Linux alternatives. I suggest considering a dual boot set-up so you can easily transition without losing the convenience of your current Windows environment.

You mentioned wanting to dual boot, which is a good strategy! I’ve had a solid experience with Mint Cinnamon after switching recently. It's straightforward and it supports a lot of hardware out of the box. If you can, set it up on a second SSD; that way, you can control which OS you want to boot into easily.
