My main rig is an AMD Athlon 64 X2 5200+, rips and converts a full movie in less than an hour. My MacBook (Penryn 2.4Ghz), rips and encodes slower, probably due to the SuperDrive not being 20x (my desktop isn't that fast, only 18x). My new rig... IF I BUILD IT... will be much faster, but I'm thinking of a new iMac, the 3.02Ghz anyone have any experiences on this machine via Boot Camp and some benchmarks? Also, how well does DVDFab utilize multiple cores? Cause I've also thought about a Mac Pro (8 cores).
