    i guess this makes sense why no one has released external graphics solution. the fastest TB is only 4 lanes. you need 8 lanes at the very least for mid~high end graphics card. TB is an interesting and promising technology, however at its infant age, most users won't be bothered until it matures to at least 16 lanes. hopefully sooner than later.

    That's only for gaming. You can easily drive multiple high-res 2D displays over 10Gbps of bandwidth via 2 PCI-E 4x lanes with room to spare. Two PCI-E 2.0 4x devices would consume, at maximum, 4Gbps of bandwidth. (500MB/s per lane x 4 lanes x 2 devices)

    Even a low-end PCI-E 1.0 1x card (250MB/s max bandwidth) can support up to 2560x1600 resolution.

    Here is a novel solution that allows you to mount an external PCI-E card of your choosing (limited to 150W of power) into an external Thunderbolt enclosure: http://www.pcworld.com/article/2484...rnal_graphics_to_laptops_via_thunderbolt.html

    If you had a PCI-E 2.0 x16 card, you'd still only need 8Gbps of the 10Gbps offered to drive it at full-tilt. Very doable.
