If cost isn't an issue, I say go nuts. But if you are worried about your shiny pennies, I would go with a P4 3.0 Ghz and spend the extra on the MB, and video card. This is also remembering that RAM is the lifeblood of any machine. 1 GB of RAM minimum, I would (and will) go with 2 GB. As far as a HDD is concerned, I would go with a serial ATA for value and a Raptor if I had the cash (which I don't). A SBL Audigy 2 is excellent value and will rock out the sounds.
Where I go a little crazy is with the video card. I think if you have the cash, I would go with the Nvidia 6800. Myself, I do believe that I will go with the Nvidia 6600 when it comes out. It looks like better bang for your buck.
Just my opinion, feel free to comment I would like the feedback.
