Celeron D are not to bad for the money. Just build one 2.8 for internet and office stuff. But if you whant to play some games just go with the xp3200. By the way that price you got is to high for the celeron 2.93 go to newegg.com about $114 with free shipping.http://www.newegg.com/app/ViewProductDesc.asp?description=19-112-195&depa=1
Hey look. Get a Socket 939 3000+ Athlon 64 and your sorted for the next year or so. The Xeon is not worth it, the good ones cost around £600, motherboards are around £300, and it's not worth it unless you really know what your doing. Damn, my mate has built over 100 computers and he still doesn't feel ready to go into dual! The Dual-Cores will be Socket 939, so when you are ready you can upgrade from your 3000+ to one of them. That's what I'm doing, and I've been researching for over 4 months Trust me.
