Hey guys, I have a 2.2 Santa Rosa mb, with 4Gb RAM, and WD 320Gb HDD. I was wondering if any of you have any thoughts on using this macbook config for DJ'ing, Mixing and creating music with Logic 8 and.or Ableton Live 7? is the macbook powerfull enuf for these applications? or would I need to move up to a MBP? and if a mbp, which one would be good? a 1) refurb 2.2 SR base MBP 2) refurb 2.4 SR MBP, 3) new 2.4 Penryn MBP, or new 2.5 Penryn MBP? would the graphics card have any significance in working with these programs? Thanks in advance!
