Only if you play CoD, Fortnite, or Destiny 2. If you’re technically inclined and don’t mind working around some issues, gaming on Linux has come a long way and can be used for pretty much anything else. I used to dual-boot Windows for games, then I went to booting Windows in a VM and gaming with a spare, passed-through GPU. But I haven’t booted my VM in months, and I play lots of games.
