NVIDIA Rushing in Stopgap HD 7970 Competitor This February?
 

AMD's Radeon HD 7970 seems to have ruffled a few feathers at NVIDIA and it looks like the green team doesn't want too much market exposure for it. A fairly-reliable source at ChipHell learned that NVIDIA's GeForce "GTX 680" part could be launched some time in February. The source says that this part could be competitive with the HD 7970, though not exactly NVIDIA's fastest next-generation GPU in the works. So it has to be something other than the GeForce Kepler 110, that's reportedly slated for March-April. At least the tiny pieces of specifications trickling out seem to reinforce this theory. Graphics cards based on this part apparently have 2 GB of memory, and its core clock speed is reported to be 780 MHz.
