    Regarding memory performance, my G5 clearly destroys the X5000 as can be seen from the benchmarks in this thread, despite what's written on spec papers.

    Indeed, but I'd still favour an ASMP solution to keep my 2nd CPU from feeling bored. After all, it is unremovably sitting there constantly drawing current and creating heat. I'd consider using a dedicated expansion card for video decoding (or transcoding) an option as soon as MorphOS supports switching off (or power saving modes for) the 2nd G5 CPU.

    I don't have a problem with that, especially if it's spare CPU power anyway.
