Hi, I know a lot about computers and a lot about writing music. I am new to computer based recording however. I was wondering if anybody could help me decide to get either the AARK 20/20+ or the Layla, or any other great sound card between $500 and $800. I have a Pentium II/333, 96 megs of RAM, and an 8 gig drive, with Windows 98. I will be working with mainly guitar, bass, vocals, and percussion. Any input would be appreciated. Thanks.
