i would expect the ti version to be the equivalent of 2 x gtx 1070 or better considering 980 ti = 2 x gtx 970
honestly i feel more inclined to get the 1070 as it seems to be a repeat of last generation, gtx 970 being the king in terms of price to performance
If the trend does continue, expect the ti version to come out Q2/Q3 2017 and cost roughly 749-799 usd or possibly less if Vega lives up to it's hype
