According to www.anandtech.com, and their testing, the Intel 2.4c Gig P4 is almost as fast as the 2.8 Gig AthlonXP. In some benchmarks it was even faster. Might be the particular benchmark they used for Quake III, and splintercell. The P4 800 Mhz processors seem to be a bit better than the AthlonXP in gaming performance.
This is where you have to go to price and see what the difference will be, and then decide what you want to buy.http://www.anandtech.com/cpu/showdoc.html?i=1834&p=10
