Packs a pair of new GK210 Kepler chips. http://www.bit-tech.net/news/hardware/2014/11/18/nvidia-tesla-k80/1
unlike most multi-GPU boards, this I feel will have a tremendous advantage. Since openCL, CUDA, and other GPGPU tasks don't require each core to share memory, you could cram a lot more processing power and VRAM into a single system. I figure whoever gets one of these would likely end up getting at least 2, since it probably isn't cost effective or easy to fit 4 boards that only have one GK210 board.
