The VGA market almost seems like it's in hibernation at the moment for the most part, as we all anticipate the launch of new families from both sides of the fence sporting 28nm GPUs, of which we know won't be until a bit of a ways into 2012.
However, it appears NVIDIA has been working on a little bit of a side project in the meantime; some more love towards its popular GeForce GTX 560 Ti. Apparently the company is preparing a new suped up release of the model that switches the GF114 GPU on the original version for the GF110 that's used on the GTX 570 and 580 models.
This in turn would give the card 448 CUDA Cores, as denoted by the supposed model name NVIDIA is going for, "GeForce GTX 560 Ti (448 Core). This compares to the 480 cores on the GTX 570 and 512 on the GTX 580. The card will have 56 TMU's a 320-bit memory interface, 3-way SLI support, DVI, HDMI and DisplayPort outputs, and will most likely carry 1280MB of GDDR5.
NVIDIA is aiming the revised GTX 560 Ti as a competitor to the overclocked SKUs of AMD's HD 6950 2GB cards while filling in the gap between the HD 6950 2GB (~$280) and GTX 570/HD 6970s (~$340). It will likely enter the market at somewhere around the $300 mark.
