I tried dual booting at first, with a clean install on a partitioned drive, just to see how well or If I really liked windows 8 Pro. If there was a problem I could just format the drive and go back to 7. Well I ran into a few problems but not really a windows 8 issue purse' but boiled down to driver issues. Now I'm only with windows 8 Pro on a single drive and haven't looked back since.
Let us know how it goes when your new mobo and clean install.
