I'm in the market for the new iMac 24" device. It's damn near impossible to find one in a store with 16GB Ram. The system requirements for programs like Photoshop and Illustrator is "8GB. (16 GB Recommended). Apparently there's something about the Apple processor that runs faster than their older Intel processor? Any input would be appreciated. I don't use Photoshop often, but don't want to get stuck down the road with insufficient RAM. Thank you.
