I really want to run Pro Tools 7.3 M-Powered on my laptop without serious lag. Is this even possible? I want to use an M-Audio Firewire 410 soundcard with a medium sized MIDI keyboard controller. Here are the specs on my MacBook: 2.0GHZ Core 2 Duo 4MB L2 Cache 2GB Mushkin RAM 160 7200 RPM Seagate Momentus Should I up the RAM to 3GB or would that be dumb? Thanks!
