Hey Tom,Great news, I'm soooo jealous! You probably have enough horsepower to give RF-X VR a go.
It was time for a new pc anyway. It has been about 5 or 6 years since I built a pc. This is the first time I have really needed anything this high end. The VR tech really pushes everything to the limit. The only thing I wish I could have done was get a 1080 or 1080Ti, but as I stated in a previous post, the cost of gpu's are just ridiculous! I was VERY lucky to get my 1060 6gb at all, let alone at a somewhat decent price.
As far as RF-X VR I am not sure if there would really be any difference as we are limited by the headset resolution.
