Regarding Titan Xp, I had one for a while, and compared to my overclocked 980 TI was about 80% faster in the sims I run. But as soon as I tried in games with Oculus CV 1, the Titan would not clock up at the same game graphics settings. If I tried to up the in game graphics settings it still did not work correctly. I spent a day or too with Nvidia techs, and sent them diagnostic files and ran tests they ask me to run. Bottom Line they could not get it to work. So I returned the card. I really wanted it to work. So for now using my 980 TI s.
