As an experiment, I set up the four outputs of my computer to play a different audio stream simultaneously. Each one took about 1% cpu usage. Next I played 5 videos simultaneously, streamed from a hard disk drive. I only used two monitors there, but that was about 4% CPU usage per video. My computer is admittedly kinda beefy, but I have no doubts that a slower computer wouldn't have trouble with the task.
