Just need a concrete answer on this. Does anybody here uses iMac to work with Photoshop, Flash, Dreamweaver, Illustrator and InDesign? If so what is your iMac's specifications and how well does it perform. I've ordered a 20" iMac (2.0GHZ Intel) and am going to upgrade the RAM to 4GB. Think I'll have trouble with CS3's performance? On a Windows PC they should run around a medium-high performance with similar specs, and since Mac is told to run better I'd expect them to run nicely.
