Ok, I am close to finally upgrading from my G3 pismo to a new G5 desktop package. I don't need the fastest/top of the line, my uses, besides standard work/email/internet stuff will mainly be the following: Photos: meager 12 gig hard drive is starting to fill up with digital pictures, and iPhoto won't let me store them on the external. Plus, I'm looking at a new 4 mega pixel camera, so even bigger file sizes are in my future... Imovie: I've got a nice a digital video camera and a 1 year old child... you do the math. My laptop just shows me enough of what I could be doing to frustrate me... I doubt I would use much more than FC express, in all honesty. Garageband: I don't know if I would give up my non computer stuido, but it sure would be fun to play with.... So here's the deal. The Single 1.8'sa are on sale for a great price due to overstocking... something like $1800 or so. But, Apple has refurbished Dual 2's for $2399. So my question is, is it worth the extra money (which is essentially the cost of a 17"display) to have the Dual 2 over the Single 1.8?? Given what I'm looking to do with it, would the Single processor be limiting to me? to the tune of $600? Thanks.
