Hello, I'm looking to buy a computer. I also want to create music with it and I was wondering if anyone had any recommendations: which software, how much HD space, etc. Also I'll need a soundcard that will allow me to connect an electric guitar and record live on HD. I noticed the SB audigy2 ZS platinum pro has an input for guitar/microphone, however it's the most expensive mainstream soundcard at the moment - are there any cheaper alternatives? Thanks.
