Test it out on an old PC, you gotta have one hanging around the house. After a couple of weeks you'll wonder how you got anything done without it.

Start now friend, it may take time to find alternatives for some of your workflow, also to find a flavour you prefer, Ubuntu, Debian, Mint, etc, there is a lot of choice. I've been slowly trying to get everything setup for a while now. Only a few more little apps and things to finish the switch. sadly I will still need windows for several VR games performance wise, some are just too stuttery on nix. I used to love Ubuntu/Gnome but KDE is a better environment, from the reading I did, for VR with an Nvidia vid card

Why waiting? Do it now. Give Linux Mint a try, or elementaryOS if you want a mac-like experience.

welcome!

to get started, download a linux OS .iso and write it to a usb with Balena Etcher. boot to that usb by selecting it in your bios/uefi (restart the computer and smash the del key a whole bunch to get there) :)

its basic, but this is the part that can confuse those who arent so tech savvy and want to switch <3
