GTX 780 Ti specifications are not yet announced. We will update this post as soon as specifications are confirmed (one way or the other).
All we know for sure is that it’s based on a GK110 and has the same design as GTX 780 and the TITAN. This card has either 2496 CUDA cores 2688 or 2880, most likely the first option though since we are just targeting R9 290X here (although there is a general assumption this is Titan re-branded, at a lower price point)
The other option is that it’s actually a TITAN with 3GB of video memory.
Jen Hsun Huang revealed that GTX 780 Ti will have a low TDP (6+8-pin power connectors) and it will support 3-way SLI.
This new GeForce card will arrive mid-November. Reviewers will get their samples today so we should learn a lot more in few next hours.

Besides the VRAM difference, I don't see the use of a Titan anymore. OC'd the 780 reaches and surpasses Titan performance already.
Hopefully the current 780s will drop in price. Or maybe this will bridge the price gap between the 780 and the Titan.
