Also does not work with my motherboard either and i5-467k (release). I am waiting for 10.8.5 source to see what they have changed from 10.8.4. Same is true for 10.9 (DPx).
Many user reported 10.8.5 works oob with their machine
One user here are using very close hardware as my mine, which is 4770k, Asus z87 pro, gtx 660ti (i use 660)
He works everything with vanilla 10.8.5
I have compared his BIOS setting with my mine and we are the same (actually he is using the default settings)
So the only problem I can think about is ES cpu...
However, after heard that your retail one also cannot be use, it's time to think about another potential issue of us
