Well, not unsurprizing, but details of NVIDIA's upcoming GeForce GT 640, GeForce GTX 650 and GeForce GTX 660 graphics cards appeared on the web.

It looks like the cheaper Kepler cards are going to start appearing in May. NVIDIA will release two GK107-based cards, one with GDDR5 memory (GTX 650) and the other GDDR3 (GT 640) and will likely replace the GTX 550 Ti. The GK107 GPU will have 384 CUDA cores, but other specs are not yet known. Prices should be around 90-110 Euro or so.

There's a GTX 660 coming in the summer for around 200 Euro which will be based on the GK106 GPU. This will have 768 CUDA cores, 64 texture units and 24 ROPs. The memory bus will be 192-bits wide and bolted to 2GB GDDR5 memory.
