I'm not after a fan boy opinion, but an opinion on which is actually better.
I'm not sure of the model of the P4, it's in a Dell system I just bought of eBay and will have later this week.
The reason I would like to know is I'm building up a budget system for a friends niece and would like to give her the best from what I have available.
The Athlon XP2100+ is also supposed to be a 1.7ghz processor.
