Jim, I guess you're missing out on the "real-time" effects rendering of FCP by having a single processor, which the duals from 500 on benefit from. I get a little annoyed tho when encoding mp3s on my 533 dual, but I'm using the LAME encoder which is great, but sloooow. I guess the "world's fastest personal computer" might save me some time over the years, but I would spend more than that time setting up the new computer - ha!
