I just bought a new MacBook, 2.16 ghz C2D, 2 gigs of RAM, using a s my everyday computer as well as for portable audio recording and production. I am running Garageband right now, and I have noticed that when I have a couple of tracks of audio and virtual instruments running, the scrolling and video performance begins to slow down and get choppy. To test this, I went to the Apple store and built the same track on both a MB and MBP- the Pro did not have the same type of video lag. I'm thinking this is due to the integrated video processor in the MB vs the MBP. My question is this- as I continue to build more complex tracks and then upgrade to Logic Studio in the next month, will the integrated video on the MB vs the MBP significantly impact overall performance? If I were to upgrade to the MBP, is the 256 mb video card option overkill for audio recording? Further, any chance that upgrading the MB's 5400 rpm HD to a 7200 rpm HD will cure the video lag? Thanks for any advice here!
