i'm wondering which would be the better motherboard for speed/SLI pci-e and with firewire. right now i'm looking at asus a8n delux sli
also: which would be best: amd or intel (i'm assuming amd)
and which of the amd is better: 4000 and under series since fx is just way too expensive right now (basically double what 4000 is and not much of an increase)
also: what other additions i'd have to get in order to make it run faster.
(i plan on making this pc a media center too with 300g hard drive in order to have all in one)
will media center sp2 slow down gaming in any way to xp home or profesional?

That of course is my opinion, but I would suggest reading reviews on the boards mentioned and then decide for yourself. Take a point of view from more than one source before you make a purchase.
