Install Ubuntu and see if you can get your games and video editing software to work. If you can’t, go for CachyOS.

Why Ubuntu first? Because millions of people have been using it for years. When something breaks, you’ll be able to fix it because someone else would have already encountered this issue before and reported it.

They’re talking about dual-booting Windows and Linux. Dual-booting two Linuxes (Lini?) should be fine.
