I need a new computer. I'm currently running a 15" PowerBook G4. FCP handles DV reasonably well on here but now that I'm shooting full-HD it simply can't keep up. I'm planning on upgrading to a system that can handle both FCP and Avid Media Composer. I've looked at everything from top of the line iMac to a MacBook Pro (probably 15" but open to 17") to a tower to getting a PC specifically for Media Composer. I work in television production so any intensive editing will be done at the office. This is for small projects, test tapes, music videos, etc at home. I'm not looking to spend more than $3k for this set-up. So, what do you think?
