" just upgraded from a 970 to a 1080, and VR is greatly improved in most games, but I wish I'd gotten a Pascal Titan X, because max settings in some games can be too much for the 1080, causing frame drops."
I'm good on the Titan X, I can wait for the 1080 TI when it eventually gets release, should have close performance with a much more palatable price point.
I have a 980 TI and it runs everything pretty well, looking at its performance I can probably wait for next years refresh. I like the fab shrink, but I really want something with HBM. I'll wait till next cycle and hope there's a consumer model from both companies that has this feature, then make my choice. I'm not seeing games taking advantage of these new features for the next couple of years any how.
