Ok, this is where you are getting into trouble. If this is something you feel you need to do, then it's time to introduce you to Mr Freeze.
Track freezing is a feature that a lot of recording software is now supporting. It is essentially a method of creating a bounced version of the track, taking the original track and all of it's effects and other loads offline, hiding the original track, and replacing it with the new bounced track, all at the click of a mouse. Unfreezing is another click away. It's a great tool for people who, for instance, feel the need to have 40 different reverbs!
Otherwise, you're going to need some serious MIPS to do all that processing.
