I'm thinking of getting an iMac G5 20" loaded with Ram. How will Photoshop perform on such a machine (using for my photography - Canon 8MP Raw Files)? Also can the built-in monitor be calibrated with a device such as a Gretag Eye-One display. If the answer is "you must be joking" than that's OK, I just thought I would ask to see if someone has tried. I am no rush to get the iMac so will probably wait for the next revision and also for Tiger to be released. Also looking forward to Photoshop CS2 - but there are other threads on that topic.
