1. How much better is the i3 processor vs the core2duo? 2. If I'm gonna shell out 1700, why not spend an extra 300 and get twice the power? Right? 3. The only difference between the old and new 1699 models is a graphics card, is that right? I mainly use the comp for web surfing. I'm starting to upload and keep my pictures but don't do any editing. I played computer games about 4 years ago, I might play the new star craft. Thanks for your help.
