Putting together GPU Workstation

I am setting up a gpgpu workstation for prototyping the neural nets. It's an interesting time in history, this will likely be the last digital, von Neumann machine I use for this work. It is a good, fast number cruncher, but it is the wrong type of machine for ANN's. It's a bad fit. 4 little islands of 4/6gb ram spinning wheels hyper-fast. The interconnects slow as mud in comparison. PCI3.0 doesn't come close, honestly PCI4.0 won't make any real difference.
My ideal is one, extremely large, homogenous 'brain'. That gives me much less work to do. Now I will have to come up with algo's to deal with very fast, slow-connect sub-nets. I will be using compression techniques to communicate between the gpu's and find ways to architect around the hardware. The 4/6gb sub-nets will have to adapt with minimal information from the rest of the network. Trying a rasterizing technique won't be efficient since the buses and HD's will be far too slow for the …
