I was thinking to myself the other day that my P4 prescott 3GHz CPU just wasnt fast enough for me anymore, and so I thought I'd turn my hands to trying to overclock it, to try and throttle a little more life out of it.
And I've now managed to get it to a pretty amazing 3.75GHz with the bus running at 1000MHz.

I've been running stability tests all day, and it is stable at these speeds and it's around 37 degrees C while idle with air cooling.
This was my first go at overclocking, so I'm really impressed. I'm sure it will go to 4GHz, but I'd have to liquid cool it, so I'll not push it any more just yet.
