There's a few videos I've seen recently -- I've also just been trekking in the Everest region and watched and read a lot before going -- that do an amazing job of conveying that summit-fever attitude.
There was an incredible documentary, which you can probably find online, called "Doctors in the Death Zone" which followed a team of doctors studying the effects of altitude on themselves as they attempted Everest. There's some pretty horrific footage of a team they encounter along the way watching their companion, in obvious distress, drunkenly attempt to reach their position, while they just wait.
Lastly, this talk from TEDMed is by the only doctor on Everest during the 1996 disaster, and it's both a great depiction of the main route, and a frightening reminder of just how dangerous it still is up there despite the number of summits and knowledge of the route these days:

The one that most sticks in my mind is this talk on K2: http://www.youtube.com/watch?v=5zkC9IMQmYA It's an hour long, but I highly recommend it.
