im waiting for the Hammer from amd then this is the set up
AMD Hammmer 2g+
1 gig+ of pc2700ram (333mhz)
ata 133 hd in raid 0 config
never get built in anything. sound video nic etc.. it will use more cpu than a card will and usally not have any extras
one of the main reasons I chose the Hammer is because it will have 3dnow, 3dnow pro,sse1,sse2 instruction sets so as applications and game make use of either set it will make your computer run faster as it gets older. (to an extent) if you get the intel tit only hase the sse1 and sse2. so anything made specficly for 3dnowpro will not be as fast on it.
and of course the normal reason people choose AMD over Intel
Better performance at a better price.
LET ME REMIND YOU THIS IS MY OPINION DO NOT FLAME ME FOR IT.
