Don't forget that the graphics emulator for Fusion is something like a GMA950 or something- basically crap. I've got Fusion, and until my student licence ran out, Solidworks ran just about okay. But assemblies over 3 or 4 parts, blocking would occur- not the same as running bootcamp, but my conclusion is why run Bootcamp at all, as you may as well just get a good windows workstation.

Like Tim says, Fusion is only really good at testing things.... :)
