So with two 27" displays, you have 5120x1440 pixels. This is enough real estate to tile eight 720p videos in a four-by-two arrangement, at the proper scale (100%). I thought it would be "cute" to actually do that for the hell of it. I mean, sometimes I need to catch up on a season of Top Gear -- why not watch all the episodes at once? Video is actually stored on the internal HDD, not the SSD (my iTunes Library's Movies, Podcasts, TV Shows and iTunes U is symlinked to point to the HDD). http://www.youtube.com/watch?v=crqkvz7OhM4 CPU Utilization? 18-20% overall (the QuickTime X process is at 150-170% out of 800%, and the WindowServer process is at 10%). I could actually run this constantly as a "background".
