New graphics cards were revealed today. We still have to see how they compare in testing. This is why many of us waited to build a computer...at the very least a price drop on the 1080s should be coming.
I'll leave these links here:

I would not expect VR to support these cards right away, but they certainly look interesting. I have a 1070 and a HoF 1080, and these are supposedly like 6 times the power.
This btw "I saw the thread caption 2070 and thought that a release date had been announced for Pantheon. Whew!!!!" was just too funny :)
Some improvements make existing games and equipment work better. Some are irrelevant until games and equipment catch up and take advantage.
I doubt if the Unity people are dropping other things to make their engine work better with cards a limited number of well-heeled people may have but not too many others for a year or two.
