Interesting read for those that are interested
I have heard people using external graphics cards on thunderbolt 1/2. From what I know it tends to be a bit hacked together. On the hardware side, you have to find a thunderbolt enclosure with its own power supply and those can be expensive. On the software side, OS X seems to take quite a bit of work, since driver support can be spotty. Windows seems to be easier to get to work.Another article: http://www.anandtech.com/show/9331/intel-announces-thunderbolt-3
I'm hoping that an affordable external graphics capability will come out of this. Anybody have insight on this?
