I didn't see this posted anywhere.

This is exactly what I want. Lucid works well for me on the desktop, so I imagine this is the exact same since Thunderbolt is just PCIe.

Thoughts?

That's very cool. Wish they had better lighting in the video though.

"Right now, however, Lucid’s external Thunderbolt graphics technology is still under development with no set release date and no official partners on board."

Thunderbolt is just PCIe

As I understand it, Thunderbolt is PCIe x4. So it's somewhat slower than a normal PCIe x16 slot.

It's more like x2.5. The host controller is fed by an x4 connection, but a single channel is only 10Gb/sec (x2.5) bidirectional. And I don't know if you can bridge together multiple channels for the same device.

It's slower than PCI 2.1 x16 but faster than x8.

So it's good enough to run current video cards like this. All you have to do is buy an external thunderbolt case to house a PC video card.

Didn't Asus have something like this a while back? Why did that not take off?
