Oh wow, yeah... didn't realize it was 20 Gbits/s for TB2 and not GB. It's not even close to as fast as currently shipping PCIe 3.0 x16, at 2.5 GB/s versus PCIe's 16. I guess external video cards are not really much of an option. Even using up all six TB2 ports won't get you as much bandwidth as a single PCIe 3.0 x16 slot.

Notice that Thunderbolt 1/2 are full duplex. With Thunderbolt 2 you get an independent 20 Gbit/s channel in each direction.
