Don’t give up on the thunderbolt - get it running in windows first. Follow the other posters advice. Use 1 GPU to start with and see the details in the link I posted. Let me know if you need my bios settings however its all about getting the motherboard to locate the card. I have a very stable hackintosh on the ASUS Deluxe as described. I’ve had it running days at a time with multiple instances of parallels vms inside it even. I’m running OSX Yosemite and followed to the letter the instructions at http://www.rampagedev.com I have had no success upgrading to El Capitan from my copy or a clean install but am pretty content: Thunderbolt, apple bluetooth mouse and (version 1) blue tooth trackpad all work (incidentally the blue tooth drivers allow the mac mouse to work on windows 10 which is great too). Good luck
