I started VR with a Rift CV1, a 4690k i5 and a GTX970, which was enough, to play Elite in low to medium settings. You are totally fine to join the club. Just don't expect to play games with maxed out settings.
I never regretted a single cent, that i spent on VR so far. Its definitely the ultimate game changer for me. Go for it
Edit: 49 here and be prepared to get the wows like being a kid again... No joke, playing games in VR is absolutely stunning.
Cheers, I'm sold - Rifts S ordered, and arriving tonight - Who needs sleep anyway
Believe it or not, it was trying it in anaglyph that sold me in the first place, I was surprised how good that looked, considering it's black and white, and wearing cardboard glasses.
cant wait for 'Real' 3d
EDIT: Yes getting used to lower settings may take a little while, but Im sure the 3d will more than make up for it.
My 1060 currently manages 2560x1440 at ultra (with a few things toned down, probs bloom or similar) and manages a steady 60fpsm which is pretty damn good.
I can feel a new graphics card burning a hole in my wallet in teh not too distant future - but 1 step at a time
