I wouldn't do it again. I had Win8 RTM with Boot Camp 4.0 drivers (which are perfect for Win7, but medicore for Win8). There are just no official drivers, and this could corrupt your drives, do very strange things.
For example I had read rights for my HFS+ from Windows, which suddenly without any reason was restricted to a few folders. Installing Paragon helped, but this corrupted Win8 and OSX partition after a few days.
Also scale support (150-200%) is very poor in Win8, which works perfect in Win7 (weird mouse issues).
Also Win8 has a feature like a fast boot (mini hibernation), which can prduce weird blue screens after a while.
I'll wait for the official drivers. Win8 is the better OS, still.
