The ideal thing to me is if you have your last pc. You throw linux on that (I recommend zorin) and you have it available alonw with your newer windows machine. In most cases I believe the linux machine will perform better. Move as much as you can to it until you have whatever little things you still need windows for. Ideally you realize you need windows for so little that you flip the script and change your newer machine to linux and windows as your backup or you put linux on your next machine and the older windows machine sticks around.
