Guitarist looking for decent base system for simple home studio. Need 16gb ram at least to start. I have HDDs as well as Creative Labs Sound Blaster X-FI Fatality Edition SB0460 and front panel SB0250. I also have a few decent graphic cards. I will need to add an audio interface. Just don't know where to start. Can anyone suggest a base system that I can build upon? Possibly a decent system that can get me part way? I have plenty of guitars ,amps, pedals, and effects. Moving from musician and composer to the next level. Thank you.
