due to the inherent bandwidth limits that Thunderbolt has as compared to the buss speeds of these GPU cards [citation needed] There probably are applications that need every single GBps of the x16 connector, but just saying "bandwidth limitations" isn't sufficient - see also the common SLI setup which switches to x8/x8 if two cards are installed.
