the cpu should be good for him :), depending on what he's using it for. but aparently you can overclock the 2400+ a bit, which is cool.
but like i said, if you dont have it ordered yet and want more bang for your buck, go with a venice core processor. they are among some of the cheapest cpu's (got my athlon 64 3000+ venice for 180 canadian) and can overclock to about 2.6ghz BEFORE you even get any heat problems. even higher if you have a good cooling setup.
the 2400+ should be good though :)
