Absolutly correct. You need to consider several things rather than just additional power.

I've attached a link showing the path that many M5 owners are taking; an ESS supercharger. It gets you to around 550 HP dependent on the one you pick. However, there are several things recommended before you add the SC. First freshen up your engine if it is high mileage; install larger clutch, some are even replacing their rod bearings which seem to be a wear item in the e39 if run at high revs or if the car has been chipped. There are several threads on the ESS superchargers in use.

As Dalekressin says it's not just the power; so if you haven't upgraded the suspension, I'd do that as well. Some also go with Stoptech brakes but you don't have to do this unless you're really going to push the 550 HP. Lastly, get rid of the cheap rear sway bar brackets that crack from the stock torque. Do a search for Beastpower sway bar brackets.

Anyway, here's the link.
