There is no such thing as overkill on a receiver and the 876 is not overkill by any means it has the Reon HQV chip that is the best video processor available in a receiver of that price range has THX Ultra2 certification giving you some really useful surround modes and has top of the line BurrBrown DACs and the list goes on something that you dont get with the 1019.
I have the Onkyo 805 (the same receiver without the Reon chip) and would not give it up for anything.
