Hi, I just set this configuration up with a GTX 770 and the Thunderbolt Apple Display is not recognized. Basically you can daisy chain everything: MBP -- Thunderbolt Apple Display -- Sonnet Exp III -- GTX -- but at the end you need another external display using the GTX video card. I have an ASUS 26' DVI. Be aware that I have a 2011 MBP with 1 port Thunderbolt 1, not 2 ports thunderbolt 2... And I'm not using Windows BC, just OSX 10.8.5. Eventually with my config, I have issues with online videos (Youtube): crash. I am considering reselling the Sonnet Chassis. Cheers, Joec
