You'll notice they specifically say "passthrough gpu." What you use on the Linux side and what you passthrough don't have to be the same and probably shouldn't be. I'd optimize for the use cases you have, also as much as I truly hate to give this recommendation: youtube has a lot of resources on shit like this (because I hate having to watch a video for something I could read). Also, you might want to really think about the GPU and its use-cases, newer isn't always better, because there are some specific ones you can buy that'll let you also run another OS 10 in a VM effortlessly :) At the end of the day this all pretty much powered by Qemu, KVM, and virtio. So if you can't find a resources for "looking glass" then just go to one of the the sources above...
