Probably the load of showing content or waiting for input, and the like. X is big. It also uses a lot (if possible an awful lot) of memory. Showing graphics can be a complicated thing which can require the cpu to do some work now and then (think placement, repainting, frequency locking, and so on and having to wait for those and catch the signals if they change). If I would have my TV viewer running (kmplayer) and do nothing for an extended period of time I bet it would show a lot more cpu than 1% still. Same with websites that use heavy and/or broken javascripts or flash. Can yank up cpu easily even for common tasks. I have a brand new oven (thats an intel mobo with a 3.4 GHz processor) and it gets a lot more noisy (fans spinning faster) when making world (in 35 minutes) or playing a dvd or a low bandwidth encoded mediastream in (k)mplayer. Anything that makes the cpu really have to work. Besides, the optimal cpu time used for any process is 100% as they all compete for cpu bandwidth (if the system would be under duress). So basically your system is doing great and is not overloaded at all. It's gravely underused one might argue ;-) HTH, Dan
