VideoCardz claims NVIDIA is planning to launch several new graphics cards this year. First up, the site claims that there may be a few more GK104/GK106 based Titanium branded cards with boost mode, and possibly also GK208-based entry-level models.
There are also whispers about a new upcoming flagship model, but it's uncertain if this will be a Titan Ultra with fully enabled GK110 GPU, or perhaps a GeForce GTX 790 with two GK110 GPUs.
Assuming that the full GK110 processor is somewhat dedicated to the professional segment, and NVIDIA made dual-gpu cards a standard, my bet is on GTX 790. You are probably wondering how much would it cost. I’m more than sure that $1000 range won’t be exceeded. This card is made as a response to AMD Hawaii cards which will arrive in two months. Then NVIDIA will most likely (slightly) lower their prices on GK110 graphics cards.
Other than that, VideoCardz also claims that the GeForce GTX 800 series may arrive somewhere between February and March of 2014, which implies these cards will most likely still be made on a 28nm process because TSMC's 20nm process isn't expected to be ready for mass production until June 2014.
