It\'s been about 2 years since I used Logic 6, but I seem to remember thinking at the time that Logic 7 ran even faster than 6 for every-day tracking.
Actually, I run Logic 7 on a 1 GHZ G4 laptop, which I also use for Final scratch ... works great for mastering mixes ... anyway, the performance is not bad! It does top out at around 10 or 12 tracks, but I think that\'s more to do with the slow laptop drive than anything else. I also pile the waves plugz on some mixes ... those are pretty intense on the CPU, and I\'ve had no real problems with it.
Anyway, I personally have no problem recomending the upgrade ... the extra features and instruments you get in V7 are well worth having to \"freeze\" a few tracks from time to time.
