Trying again in a different way… GeForce now +Steamdeck vs steam machine

My PSU and my motherboard died, so I’m going to sell off my PC for parts. I have been waiting for the steam machine, but at this point, I’m curious if just the steam deck docked, plus GeForce now with one of the higher tier subscriptions is a better move than rebuilding the PC or waiting for the steam machine. My specific motherboard is almost $400 to replace because it is discontinued, so that is why I’m selling everything else off.
