Sorry for the jaggies, but this is how I got it (someone clearly doesn’t know how to resize pictures). I will make this post as short as possible. Yes, I know it has the GeForce GTX logo upside down.
Most importantly, the GTX 780 will use the same cooler as the GTX TITAN. Moreover, it is equipped with 6+8pin power connectors.
NVIDIA GeForce GTX 780 is featuring GK110 GPU, which holds 2304 CUDA cores, 192 Texture Units and possibly 48 Raster Operting Units. This card will arrive with 3GB memory by default, but it is believed that we could see 6GB models in near future.
According to Fudzilla, the reference model should cost €500 / $500.
