I’ve been editing DV25 material on a iMac 2.0ghz with 2gigs of ram and the standard graphics card that came with it. Motion and color runs fine for me for wedding and small corporate stuff. The reason I mentioned those programs are because they are the most taking on the graphic card. Rendering in final cut using the dynamic button is fine for me, but maybe not when a client is expecting close to 100% quality at all times.
The reason I choose the iMac was for cost versus Mac Pro, but also a trial run to work with FCP, and I must say that the interface is much cleaner and intuitive.
I come from about seven years working on a custom made pc running Premiere Pro 1.5 on a Matrox RTX100 system. My main reason for leaving PC was the constant crashes, blue screen of death.
