the AMD Athlon Processors are the most
suitables for sound editing, recording, encoding, decoding; so if you are going to
use your PC intensively on sound-issues, go and buy an AMD Athlon 700 MHZ. This Athlon is also more powerful than the PIII with same clock speed and additionally cheaper, too. Besides of that, if your harddisk isn't fast enough, go and buy a fast harddisk. Also, you should have 128 MB ram, if you dont like waiting for minutes, like me, while you edit or modify a longer wave file.
Thats all. I hope, i was helpful...
