If you can get the dual 3 it might be worth it, as you can always add RAM and hard drives later. Same with the AppleCare, and a new graphics card if the 7300 isn't great and/or if you get into 3D. 4GB from OWC or Transitl ($408 for 4GB Apple Spec
here) to add to the 1GB should be fine for now. 2x 750GB at Fry's ($220 right now, plus Tax and S/H) or 1 750 with a TB added later. The Dell monitors are fine, but not great. Apple's are nice, but much more expensive. I've heard good things about the GateWay 24" ($599 right now), but it's GateWay, so who knows.
