Ordered 5x 60cm versions today.  Figured, what the heck.. I can always lay GPUs on their side outside of my rig if too long.

What PCIe version are these?  1.1, 2.0 or 3.0?  Cause bandwidth doubles in each.  Most PCIe slots are 2.0 I know, but plugging into an x16 PCIe 3.0 slot should yield... PCie 3.0 bandwidth?

I ask because I also do some CUDA computations, which requires some very high bandwidth.  It would double my calculations is it is x1 PCIe 3.0 over x1 PCIe 2.0.
