yes it is, but 1) 9-series are harder to hack (little info from people who have successfully built a hackintosh on 9-series boards, especially Asus); b) Asus boards have disgusting DSDT tables in their bios - even Clover may not help you there - you might need to create a DSDT patch manualy.
I would consider GA-B85-something if you're not planning to overclock, or GA-Z87-something if you are.
