I'm in the same boat as you in regards to hardware, and although i'm confident it can be done, i'm looking for an easy to follow guide to help me through it. If my understanding is correct, the main issue is configuring the motherboards power management in line with OSX's set up (Auto power off, sleep mode etc).
This is the guide i've been trying to follow..
So far, I've descovered the B85 is a UEFI setup but i can't find a pre made patched BIOS for it, and for an unknown reason my computer wont open the UEFI patching utility posted on this thread http://www.insanelym...ching-utility/ so i'm falling at the first hurdle.
Asus vanguard B85
Asus GTX 780
Seagate 2TB BARRACUDA 3.5" SATA-III Hard Drive - 7200RPM 64MB Cache (OSX Install Drive)
Samsung SATAlll SSD 250GB (Windows)
Corsair 16GB RAM
I'm really hoping someone out there can help!
