What would the $1200 upgrades entail? Seems that you could build a machine with enough power from scratch for around $1200.
I'm also not trying to match minimum spec, if I'm going to spend money upgrading for VR, I would want something that will last at least a few years, so I looked into (reasonably) top-of-the-line hardware.
970 is really not that much slower and then the whole machine is like $600 instead of $920.
