I am planning to upgrade from a Pentium II 350 to an Athlon or thunderbird 1 gig. I realize I need a new mother board and perhaps memory. But, I have not found any information on the which processor is best for me. The majority of my use will be processing audio files to remove clicks pops and other noise. The rendering time for this operation now is typically 1 minute for every minute of music on my pII 350. Any thoughts????
