It is a crying shame, but all the thousands spent on the Power Mac 4-digit models is pretty much down-the-drain for running these kinds of programs. Apple moved to standards like AGP video cards, etc. after that line.
I initially 'switched to the dark side' after being a Mac nut since 1986 strictly for financial reasons. After dropping major cash for a IIci and then IIfx with 19" monitor (his idea), dad just wouldn't pony up $7k for a Power Mac with video editing.
