Knowing what country you plan to do this work in would be useful as well.
Last (for now) are you talking about rendering video, 3D objects, what?
you are right. the reason i ask is to know the amount to i should have in mind. i am from Nigeria, and the most common OS is windows, i intend to start with 3d object,(cinima 4D,blender, 3dmax etc). then move to video rendering
