So Im starting to configure a Mac Pro for purchase after this sites suggestion that I should bite the bullet and just get a Mac Pro. I dont know that I really need 8-core processing. Once again can I justify the $500 upcharge. I know that it will be nice for the future and all, but if I stick with FCP 6 Suite, and Adobe CS3 will I need the 8-core? Once again just trying to justify spending more Moines.
