I'd love to post the release of the GeForce GTX 780 Ti, the new flagship card from NVIDIA, but despite it already being November 7, 2013, the launch hasn't happened.The funny thing is that some OEMs, like Micro-Star International, launched the products only to pull off the pages soon after.
I can understand their eagerness. The GeForce GTX 780 Ti is, after all, supposed to be NVIDIA's answer to AMD's Radeon R9 290X. A card stronger than it and the GeForce GTX Titan and, really, all others out there.
Essentially, the GeForce GTX 780 Ti is the ultimate GK110-based graphics card, with 2,880 CUDA cores, 3 GB GDDR5 VRAM and 875/928 MHz clocks (7 GHz for the memory). All for $699 / €699.
At some point in the future, 6 GB models might appear, but it's not a sure thing. For now, stay tuned for when the new boards do show up later today.
