ok well im running windows xp with a nvidia 512 graphics card with 2 gb of ram and a pentium 4 ht with 2.8 ghz. Never have a problem playing WoW or other high end games until the system idle process came out of no where. Im playing a game or something that requires alot of cpu usage and the process goes hogs my cpu and sources and lags up my computer even when norton is running which uses a farily large amount of cpu

I may be completely wrong but I think that was just an added line to the process meter to show how much of the system resources are free. ie. system idle process is equal to 100 minus all other processes

Like I said, thats just what I think, see if anyone else can confirm or deny...
