As the title says, i'm going into the video editing business. I've been using adobe premiere for all of my movies, but now i crave my first mac. My predicament is that I have a budget of around $2500, including tax (California). I've basically narrowed it down to the basic mac pro with an old CRT that I have laying around, or a completley maxed out 20" iMac. Any suggestions would be helpful. thanks!
