As merely an end user, I need someone (brainiacks, coders, et al) to help explain to me whether or not certain applications will work any faster with a G5 as opposed to a G4 - namely Final Cut Express, iDVD, and iMovie. Pardon my paraphrasing here, but I've heard that these applications have simply removed Altivec in order to make them work more efficiently with the newer 64-bit G5s. Bottom line: Will these apps work faster on a G5 (Dual 2.0) as opposed to a G4 (Dual 1.25)? Is there a difference within these apps depending on what computer they're used on? Thanks in advance as always!
