Yes you will need extra processing power. The current Dolby Atmos standard allows for up to 34 channels, 24 ear level and 10 height channels. Most of the units coming out seem to only do 11 or so channels such as the 8802A with its 7.1.4 capabilities.

Atmos for home does not use real time rendering of sound objects as it does in the cinema. Home delivery requires a remix/downmix of all height channels into the 4 channels prescribed for home delivery. This necessitates an additional remix in the dubbing stages (which is one of the reasons you don't see many Atmos home releases right now, due to the added cost). 7.1.4 is the practical limit for now.
