+Alive Shockwave No one knows. My wild guess is but "maybe" when the GTX 1080 Ti. I feel confident the price of the GTX 1080 (non Ti) will drop at that time. But they big question is, when will the Titanium variant be released. No idea when it'll come out and I doubt the price drop of the 1080 will be significant.
Personally I also find the x80 series to be a poor value, once the x80 Ti releases. I only like the x70 and x80 ti cards. If you currently have a 980 Ti, then I should that you simply hold onto that card and save your money. Whatever you end up purchasing, you could also buy a EVGA card, so you have the option of the EVGA 90 day step up program ( http://www.evga.com/support/stepup/ )
