Tuesday, October 29th 2013 Discuss (76 Comments)
NVIDIA's response to AMD Radeon R9 290X, the GeForce GTX 780 Ti, is likely designed to be faster than the company's GeForce GTX TITAN graphics card, at a lower price, although it turns out that it won't end up anywhere close to AMD's pricing. The GeForce GTX 780 Ti will be formally launched on November 7, 2013. It will be priced at $699.99. The card is shaping up to be an overclocked GTX TITAN, based on the same GK110 silicon, and with 6 GB of memory. The company will also launch a game bundle along the lines of AMD Never Settle, which will include Steam/U-Play keys to Batman: Arkham Origins, Assassin's Creed IV: Black Flag, and Splinter Cell: Blacklist.

It appears the 3GB versions are coming out first - maybe 1-2 months down the road the 6GB versions should appear as well.http://videocardz.com/47719/nvidia-launches-geforce-gtx-780-ti
There appears to be a NDA or no info on the 780TI 6GB so far.
