Well, I can tell you it can do all of this at the same time and still play a fluid game of COH:

We had the TV tuner going, watching a DVD, had the built in camera on, a City of Heroes game running, AIM chat, and a few IE windows surfing at one point using the 17" display and a 19" external monitor. If a person really needs more than that running at the same time there's no hope for them. It's safe to say it will hang with a very high end desktop.
Luke is here @ work with AIM, Outlook, couple of IE windows open, and World of Warcraft running most of the day every day in a dual display setup on his 9860... probably 18 hours a day flipping between game and work tab key style

. Makes you wonder how a guy so innocent could get punched in the face lol.
