I'm about to purchase a new iMac. I'll primarily be using the computer for Flash, Illustrator, Photoshop, and AfterEffects, but I will be running the CS3 versions of these programs. Would the i7 Quadcore processor give me any added power with these programs? Are they optimized for multi-core processors? Do I need that kind of power or should I stick to the Core 2 Duo? Thanks!
