I have done some searching here for thunderbolt discussion, but did not find an answer. Basically wondering if there is a thunderbolt pci-e card that will work in 2010-2012 mac pro? The mac forums say no, but we do have some things here that mac says are not possible. My understanding thus far is that thunderbolt is a cpu-motherboard technology, but still hoping there is a pci-e card that can fill this role. Any information is much appreciated. Thanks.
