Boost (and power) cost money. It depends on how long you want your engine to last. An intercooler will help your engine last longer, and let you run more boost.
"Let you run more boost"? How? What I'm getting from the other replies is that the only real difference it makes at a given power level (for a given total air mass packed into the cylinder, that is) is the detonation issue.
