This is the problem, you need something before building your full dive computer around 2016-17 (the best time to build a vr dream machine.) But if you do do anything now it'll mean rebuilding in less than a 2 years which means I won't get my moneys worth outta the top gen stuff now. Welcome:
Caelum's Guide to making a mid-range VR computer for 2015
I tried to come up with a better title but "the drive for a VR hard drive" just wasn't sticking.
So what you're probably looking at is a $500-$1,500 tower for your (we're assuming although this could easy transfer to other HMD's of similar caliber.) This will play the new gen games and demo's at medium to low quality with high frame rates. Now medium to low!? who wants that. and that will be the sad truth of this guide, the important thing is to be getting the 75 frames per second with millisecond tracking to photon latency. The graphics will help but all in all that's what will get you good vr experiences. I would love to bump it but all ready what your getting won't have seen it's full life before you'll throw away that half juiced lemon for a brand new one. Remember this is a tide you over PC so don't get too excited for what you'll get out of this. You'll most likely have to build it yourself unless you have someone do it for you. I believe places like memory express do this. So; without further ado let us begin with the CPU.
