I switched over to FCP from premiere 1.5 about a month ago. One of the disadvantages was I couldn't get PPro to recognize a dual processor so I was running on a "single" 2.4 AMD. Even though this is a good processor it was still to slow to handle PPro. There are some good used G5s for sale that will run FCP 4.5. I picked one up locally for $1650 Canadian. It's a 1.8 dual with 2 gigs ram and a second hard drive.
