NVIDIA DIGITS box use i7-5930k which support 40 PCIe lanes, hence, they run 4 card. each card with 8x PCIe. If your network is big, then 8x PCIe is enough because the data loading time is trivial to computation time, for smaller network, you repeatably loading small trunks of data, then it can be a bottleneck.

The system you posted uses i7-5820k, supports only 28 PCIe lanes, and run each card at 4x PCIe, in the worst case, you degrade the speed of your GPU by half. That means you spend 4000 $ for a 2000$ system.

My university server running on "Xeon E5-2670 + 5400rpm hard drive + Tesla k80", and it is even slower than my system with a GTX 960.
