i am considering an upgrade,

i would like to get maybe Xp2400+ Tbred or a P4 2,4Ghz. their prices are pretty much the same here. I checked the performance on sisoft 2003 , it may not be very accurate but it seemd the xp was better on most things and it was only 2ghz. whichi should be the best option, then i wll discuss the MObo thansk
