The site claims the card will feature 480 shader processors (240 x 2) and says NVIDIA will release at on January 8, 2009 at CES.
The card allegedly has a 896-bit memory bus (448 x 2), 1792MB GDDR3 memory (896MB x 2) and a TDP of 289W. These cards should be very fast and there's a rumour that the first previews of the GeForce GTX 295 may hit the web later this week.
