Ubuntu is fine to be honest. If you stay with the big three: Fedora, Suse and Ubuntu there is a ton of documentation and have actual companies that use and develop for them
You shouldn’t have much in the way on issues with a NUC since Intel targets Linux with it and most of their drivers are in the kernel.
Haven’t got into GW2 at all. GW1 gets a nice 60+ fps in 90% of the areas, drops to 30 or so when theres a big mob and lots of stuff on screen. I’m happy with that (would prefer 60+ all times but you know) plus the size of the nuc i love it.
Thanks for the replies peoples, Im going Ubuntu 18.0.4.1. I’m just about to make the move.
