jimbyjoe -- if you dig thru this site you can probably extrapolate macbook vs macbook pro performance.

OK, i did a bit of testing on my wife's Macbook (not Pro) tonight (2.16Ghz, 1Gb Ram, stock everything). The DP project had:
- at least 14 full-time mono tracks (with about 6 others)
- at least 12 stereo aux groups (6 Master groups + 6 FX busses)
- each mono voice and aux had an average of 2 effects or processes on it. I made sure I was liberal with my use of delay and long reverbs.
- 4 inserts on the master
- plus 4 tracks with automation
I then recorded a guitar split into 4 mono tracks (through a very bodgy jod with some pedals and some mics), whilst playing all this back. There was no sign of strain or anything. I did some activity monitor screen grabs. When the maximum number of tracks were playing back and the 4 mono tracks were recording, this is what Activity Monitor said:
CPU
User: 45%, System 17%, Nice 0%, Idle 38%.
System Memory
Wired: 209; Active:176; Inactive: 369, Free:268 (all MB)
Disk Usage
Reads in: 71292; out:42927; Reads in/sec:10; Writes out/sec: 2
Data read: 3.73GB, Data written: 1.22GB; Data Read/sec:1.85MB, Data Written/sec: 256KB
Compared to when I was just playing everything back and had several other applications open, the CPU usage was at 45%, 12%, 0% and 45%, it doesn't seem so bad all the recording and playback (no others apps).
I don't have too many projects with that many tracks and plugins, though the reason to buy a Macbook Pro - "i might need all that performance one day...."
