My college is selling the previous 17" MacBook Pro (Brand New) AND Applecare ($239 value) all for $1899. Considering that the educational price for the current 17" model is $2599 (without Applecare), I'm tempted. I currently have a Dual-Core 2GHz PowerMac G5 with 4.5GB of ram. I'm wondering which of the two will be faster. My main apps are CS3. I occasionally deal with 150MB+ files in Photoshop. Thanks!
