I still have Win10 on a laptop just to drive a scanner that has no Linux drivers.
My media server and main box both run Linux Mint. I switched a year and a half ago, and love it. I'm not much of a gamer, but so far, I've played FO4, Portal, and Bioshock and a few other games with no problems. I use ModOrganizer 2 to mod FO4 and it works fine.
I'm a stupid old man, I made the switch, and you can too.
