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
