I am considering purchasing a new 24" entry iMac for my wife, and I am wondering if it will perform any better than my original (first gen) Mac pro with 2xDual Core Xeon CPU's and 6GB of RAM? If so I may pass the Mac Pro down to her and keep the iMac for myself ;-) I have 2x24" Dell Monitors connected currently to my Mac pro, and there is really nothing I have currently on the Mac Pro that I would need on an iMac other than it has more Ram that the 24" iMac. I do quite a bit of stuff with Aperture and iMove so maybe the graphic performance and CPU upgrade would be better? Thoughts?
