In the latest issue of electronic musician, they had a cool article about optimizing your PC for Audio.... I went to the website ( http://www.emusician.com ) to try and link to the article, but That is The ONLY article they didnt have available online. weird.... but anyway, you could also go here: http://www.bluelifeaudio.com/~pcconfig/
one tip that Emusician had that stood out was that if you can make two different hardware profiles, one for casual use, with everything on, and one for audio, with everything disabled in the device manager except the bare bones setup for running the PC and rec/playback of audio, you can greatly improve performance. ( like disableing the modem, dvd rom, floppy drive, I forgot what other stuff I disables, but it ended up in a 10-15% performance increase with a big file playing.
