Most of Nvidia's GeForce GPU lines of the past few years have included a dual-GPU model, and it seems the 700 series will be no exception. Sources have told VideoCardz that Nvidia is working on a new high-end graphics card, most likely the GeForce GTX 790, designed as a response to AMD's upcoming 'Hawaii' graphics cards. The GTX 790 is said to include two of Nvidia's top-end GK110 GPUs, used on the GTX Titan and GTX 780.
