thorpee I think so, but so many bug fixes and active development are occurring at the current time, that I don't think one really should.
Re: GTX970, you can, but the GPU in it is an AMD so the driver will be completely different. I wouldn't bother tbh because nothing in the display chain will be the same, the driver and the display both. They're using Wayland for the overall system, the KDE desktop mode is still using X.org.
I hope they release a good dock for it eventually, I want to see how the output to my display is and tbh, it'll be easier on my eyes/neck if I can sit more comfortably.
