Hey, I'm facing the same dilema. I'm gettign one for my Birthday, I can't wait ... all the music I can do with a G5, the thought of it makes me dizzy!!
I will hopefully get one of the Dual, Dual core 2.7's if Apple ever release the damned things.
The main advantage is in processoor cycles, I think you'd be able to have more reliable audio syncing, assuming you've got a lot of data to crunch though. I doubt it'll let you use more ram but I don't see that as a problem. I only have 1.25GB Ram in my current G4 and I use 40+ instruments with little difficulty, so being able to use 4GGb would be just lovely.
Bottom line is get the best possible.
