Anyone know if there has been a change in configuring a PCI expansion chassy to work with Graphics GPU. I know this is a major reason people have been hoping for a new Mac Pro. If they solve this problem you could build out from your imac. I was hoping there would be some news on this at NAB.

an expansion chassis for GPUs over current Thunderbolt tech wouldn't work too well because Thunderbolt is a 4x PCIe connection. Each GPU is 16x. Even the PCIe expansion chassis's are a compromise because the most common config - four 16x slots; is still sharing four 16x GPU cards over a single 16x PCIe connection to the computer.

Not every workload has identically demanding bandwidth requirements. Even Thunderbolt's bandwidth (at least when working at 2K or below) is more than sufficient to send a video stream to and from a GPU in real time. It's unclear to me if substantially more than this would be required.

It isn't sufficient. Stick a gpu in a 4x slot and see how well it works in resolve.
Hint: not well at all.

Stop waiting for miracles (a new mac), buy a z820, and you will have 7 slots.
