As far as linux goes, it's made huge strides since I started messing around with it back in the early 90's and it's a capable windows replacement with a few caveats. Namely, if you don't use hardware known to work with linux (and sometimes only redhat/fedora or ubuntu) prepare to spend time trying to make your shit work. If you don't feel like it or don't have the time, don't bother with linux period unless you like the problem solving process. Really, I would say if you just want a computer that you can turn on and simply use for day to day shit, get a chromebook or low end win 10 laptop. Gaming on linux is lightyears better than it used to be, but if you're going to jump into that particular arena, make sure you have compatible hardware or you probably will be doing the problem solving thing again. As has been mentioned, Nvidia has been great at proprietary linux drivers for some time now, I would go with them over AMD still.
I personally don't have any linux partitions on my main machine, but I keep an old core 2 duo quad boot with 4 different distros on just to fuck around with (

Arch). Linux can be a lot of fun
if you enjoy messing with it. If you try it and you don't, ignore spergs who champion it as the be all and end all of OS choices, cause it ain't and never will or should be. Windows has it's issues, but it still has the best support because it has the largest market share and thus, support from manufacturers.
