As a video editor, I hear a lot about the Mac Pro with duel Intel Xeon CPUs. Right now I edit with a PC with an i7 CPU and it works very well. Is there any reason for me to consider changing to a Mac Pro with Intel Xeon CPUs? These are very expensive computer and I wouldn't want to make a move if there wasn't a BIG improvement. Plus I have never seen a comparison between the i7 and the Intel Xeon CPUs. That would be interesting to see.
