You can run it but i'd forget about 120Hz+ modes and you may need to scale down on the quality settings on some games. It's usable though and you can upgrade your GPU at a later date.

Valve is pretty much the only reason Linux VR is even remotely a thing. They're pretty much bankrolling the whole thing by employing and contracting people to work on the kernel, Xorg, Mesa, Wine, Wine related libraries and of course SteamVR and Steam for Linux.

Vive Pro with wireless is decent but is going to run you about the same price as Index even if you find a good deal. Vive + DAS + wireless is kind of passable but the screen is outclassed by everything modern. Both of them have kind of meh tier mic and speakers compared to Index.
