Rumors about NVIDIA's upcoming GeForce GTX 600 range started to surface. TPU  writes the GK104 will end up in two more cards in May: the GeForce GTX 670 Ti and GeForce GTX 670. These two models are anticipated to be launched in the $400-$499 and $300-$399 ranges, while a dual-GK104 GeForce GTX 690 is expected around May-June.

Also in May, NVIDIA will launch desktop discrete graphics card SKUs based on the GK107 chip, which makes up its GeForce GT 650M/640M mobile graphics SKUs. Following this, some time in Summer, NVIDIA will release a new chip, the GK106, which will make up the GeForce GTX 660, which will be out to compete with Radeon HD 7850, and HD 7700 series. It looks like NVIDIA is waiting on current inventories of GF114-based SKUs to get digested, including those of the recently-launched GeForce GTX 560 SE, and is hence in no hurry to launch a new GPU to capture the sub-$250 price-points. Besides the dual-GPU Radeon HD 7990, there's nothing new in the works, at the red camp that we know of.
