Hi, I'm ready to graduate college and I'm looking for an ideal graphic designer's configuration for an iMac. I don't want to spend extra money on hardware that I don't need, so I'm looking for some advice on the CPU and RAM. It is a two-part question. I will often multi-task with programs like Flash, Illustrator, and Photoshop with large file sizes. Right now I primarily use a PowerBook G4 with a 1.5ghz CPU and 1gb of RAM. 1. I can either get the 2.4ghz or 2.8ghz CPU. Is the extra .4ghz worth $250 for me? 2. I will often be running RAM intensive programs, but is 2gb enough for now? Upgrading to 4gb is an extra $700, which seems extreme, but I may need it. Is it worth the money now, or in a year or two could I get the upgrade then for cheaper? Thank you very much for any help you can provide.
