4 x GTX 1080


I trained quite smart chatbot using 800Mb of native Estonian language movie subtitles. I used DevBox as reference for my machine. I had one maxwell Titan X.

Now I want to put together a new machine. (because left previous company)

  1. Can you tell if I can put together four 1080 cards on ASUS x99-E WS? (Dont have budget for four pascal Titan X’s) I use Tensorflow and Caffe.

  2. Is it possible to use four cards simultaneously for the same optimization? Do I need 4-way SLI or not? I am not sure if SLI is even needed for non-games like CUDA.

  3. There are different manufacturers like MSI and Gigabyte. Should they all have same support for multi GPU or not?
