For those doubting the usefulness of these rigs, I can say that for GPU rendering numerous of these are in use by small sized studios and freelancers. The bottleneck of the slow PCIe connection is nothing compared to the render times per frame in most cases. It's only when a frame takes less than a second to render that you notice. They are very popular with e.g. Octane users. The only thing to be aware of is that some motherboards do not play well with this and will not recognize all cards or will not run stable with it attached.
