I'm in my preliminary research stage trying to put together a machine for a friend with a similar setup to yours. I'm wondering if you might have a link to some documentation on the GIGABYTE GA-Z77X-UP5 TH or if you were piecing it together as you went along. The goal of using thunderbolt is for high speed data transfer and taking in video and outputting it to show live color correction. He's making it work via a MacBook pro, but is trying to get a more reasonable setup. The problem I'm running into, is I haven't built a hackintosh in about five years. And I can only find one guide that has no discussion surrounding it. Also, this mobo isn't listed in the Wiki, which was a huge help to me in the past. If you have any links that could point me in the right right direction, I'd be grateful. Thanks!
