I don't know how ANYONE can come to the conclusion that he overacted in The Godfather films. If anything...he was incredibly restrained.

As for Scarface...I don't think he was overacting so much as the character was just flat out "over the top." Pacino was going for an over-the-top character with Tony Montana, and he pulled it off flawlessly, IMO.
