I bought a Mac Pro when I started school, I'm looking to do a lot of media creation. (Video, audio, graphics) But it's only a Duo core, and I only have 10.4. It is lacking behind a ton compared to these newer models. I don't even have the blue tooth dongle. I haven't done anything to it, but I now have the money to upgrade it. Should I? I know it'll work for what I want to do, but it would work a lot better if I have the 8 core. I'm thinking I'll upgrade this and use it as a second computer, after buying a MP with a better processor. Is this a good idea? Is it possible to upgrade the processor, is it worth the money?
