What Os for ASRock VisionX 321B and xbmc

Hello.
I have ordered a ASRock VisionX 321B. And I am going to use it pretty much only for the magnificent xbmc
What operating system do you guys recommend. I am ok with computers but is only used to windows. But I noticed there are nice guides here so I think I could manage to install linux, but it seems it is more work to get the latest drivers etc then. What is the recommandation, windows or linux?

Thanks
