Hi everyone...I need advice for a friend who wants to buy her first Mac. She wants to get into a little Photoshop and some light video editing as well. I am caught between the 2.66GHz and 2.93GHz 24inch new iMac models. Do you think the 2.93GHz is necessary? Also, I was checking out the different graphic cards. The less expensive model has NVIDIA GeForce 9400M with 256MB of shared DDR3 memory and the other one has NVIDIA GeForce GT 120 with 256MB of GDDR3 memory. I know you only take advantage of the faster processor and more ram, etc with certain programs. She wants it to be super fast, but is the more expensive system worth it considering her needs? I have a 4 year old G5 that still works awesome for me, but I know some of you will be far more in the loop to give advice. Thanks in advance for any info!
