I've decided on a Macbook Pro for university: there are a couple refurbs of this model on Apple's site for $1,999, an attractive drop in price from what a new one would cost. I don't strictly need the difference between an 8600GT and a X1600. I can upgrade it to 2 GB myself(I understand the new ones will go to 4). My question: is this a bad deal? I know Core Duo means 32-bit, and I understand there's a fair performance difference between a Core Duo and Core 2 Duo of the same GHz speed. Also, I assume yes but did the 17" Core Duo MBPs have the 1680 x 1050 standard resolution? Last, heat. I haven't seen many people post about heat on their Core Duos, but I seem to remember Core Duos run a lot cooler than Core 2 Duos. If the heat situation with Core Duos is significantly better that would affect my purchase, so anyone with a Core Duo Apple portable, especially a 17" MBP could you post some temp readouts? Thanks in advance!
