I would like to ask a realistic question.
Lets just consider single GPU numbers without dual GPU solutions, for guys with power need just for a single screen.
Considering what we know, the Titan will be about 70-85% faster then the current top end GPU GTX680.
We speculate that the GTX780 will bring in about maybe 15-20% gain over GTX 680.
would whatever comes next after 780, the 880s be able to match the raw power and speed of the Titan?
Even tho if it did that will be a long time from now, probably soonest 1.5-2 years, at typical price range of 500-600 for top
end model. If 880s will "just" match same power of the Titan, by then I think having the same power for the past 2 years for the additional
300 bucks over the typical high end price of 500-600, is not really all that bad considering you will have a really "futureproof" card that might last you for at least 3-5 years.
That is why I'm really considering getting one for just for the fact that the future tech is slowing down, and power gains seem to be just incremental over each generation.
Lets not put out AMDs offering out of the question either, I'm only looking for best,fastest at a given time, with reasonable price range.
