I had a couple of questions on the performance of the new iMac. I was looking at the new 24" iMac with 3gb of ram and upgraded graphics card. I am a photographer and would mostly be using the computer for Photoshop and Raw conversions in C1. How would the new iMac compare to the previous non-intel G5 towers? How would it compare to the current MacPro? I already have a 24" monitor but the idea of dual 24" monitors sounds pretty nice. The way I configured it I would also save $1000 over the MacPro and have the extra monitor space. I am currently using a Black Macbook. How would the performance of the iMac compare to my current machine? Also I know graphics cards are always a hot discussion around here. Is it worth the upgrade? Thanks!
