Hi, I am going through the process of setting up bootcamp and i would like to know how many GB i should allocate to windows? I have a new macbook pro 15inch. I will be installing the 64-bit windows 7 and intend to use it for Revit, auto cad, photoshop etc. I would appreciate it if anyone can recommend how much space to allocate?! As I have no clue on these things. Thanks!
