I am about to purchase a new iMac for an employee who would be doing much of my current work for me. In addition to alot of web design and advertising layout, I do a little bit of video editing (AVCHD) in iMovie and/or FCE. Probably 10-15 movies a month that run 5-10 minutes each. I use a MPB 2.8 with the 9600 in it, which works fine for my needs. Which video card in the iMac would be the most comparable? the 120 or the 130? Is the 130 worth the upgrade? I will probably steer clear of the 4850, because of all of the problems. It wouldn't be worth the issues to me. Thank you.
