Hello, I am purchasing Mac Desktop Computer and I would really appreciate any advices. I make animation and I need to run mutiple graphic tools (Photoshop, Illustrator, Final Cut Pro, After Effects etc. - two or three at a time) and preferably be able to render files at the same time without computer getting slow. And the faster they render the better. However, it is going to be for a very small home-based business. Can IMac manage handling those tasks? Do you recommend getting MacPro? I am deciding over: IMac 2.4GHz Intel Core 2 Duo MacPro 2.66GHz Dual-Core Intel Xeon Thanks!
