I bought my G4 1.25DP(mirror?) about8 months ago; and now I'm wondering why. I thought it would be a good idea for DV, using FCP and DVDSP; I thought applications would be optimised to make use of Dual Processors. I haven't seen any reference to DP optimization on any app so far. Was I duped, am I getting any benefit from that second Processor; can't say my machine feels terribly fast.
