hello- I am loving my new mac pro 2.66 / 2GB Ram computer. Everything runs smoothly and powerfully...except one little thing. Since I am a little paranoid and somewhat OCD...I decided to run visualizer in the normal itunes window while playing music. It runs smoothly for the most part, however it seems to glitch every once in a while as if the computer can't handle all of the math. Kinda like when you run a computer game and you hit a heavy graphics part and it chops up. What gives? C'mon Xeons!! Am I just being way too picky? I have run 4 HD videos at the same time, yet I get a little choppiness with itunes visualizer?
