I have a MAC G4 that I bought several years ago, Iwas thinking on buying a MAC PRO to have more than enough memory to the kind of work that I am doing. Most of my work is doing kind of experimental projects, short films that I produced myself, and I don't have like a full time .business doing this, although I charge for works that I do to several people but this is once in a while. But I realize that even with the kind of work that I do, my MAC G4 its getting to short for me and I getting not enough memory even to the kind of work that I do.. It is a good thing to buy the MAC Pro or not?
