Yes the 780 ti is better price to performance, what I was saying is that even though its price to performance ratio is better than R9 290x's its still a lot worse than say a 760 or R9 280x, also the most recent rumours I've scene concerning the 800 series is that they will be released October/November (seems more probably November from what I've read) this year, or early 2015. Also, recent rumours point to the 880 and 870 using the GM204 GPU, which is the equivalent of todays GK104, which is from what I've read is speculated to be released in autumn, what somewhat disappoints though, is that GM210, GK110's successor will be released sometime in 2015, and with it will come a more powerful 880 and Titan-esque GPU, which leaves the autumn maxwell release a bit unexciting for me at least.
