It seems Nvidia is planning to launch yet another GeForce GTX 1060 variant, one with 5GB of GDDR5 memory to go along with existing 6GB and 3GB models.

Nvidia has not officially announced the new card. Instead, Expreview yesterday posted an image of the card's GPU (GP106-350-K3-A1), claiming the GeForce GTX 1060 5GB would be destined for internet cafes in China.
