Which one did you go with any why? Did you go right to Tesla's or start with the high end GTX cards?

We are about to purchase 2 8 GPU HPC systems or a single 16 GPU system and are doing some comparison's on the systems and what they can provide.

I like the attachment unit that uses a PCIe extender card to add 16GPU's to an existing system, I could use this on a Mac Pro and have 16GPU's on top for an existing 24 core Xeon.

You're going to have 16 high end GPUs plugged into 1 PCIe slot? I don't think 1 slot can provide the bandwidth 16 fast GPUs require.

I heard about the tech last week. I don't know all the details yet. It might require multiple PCIe slots on the host rig, not sure.
