That receiver is plenty powerful, what speakers are you planning on connecting to this receiver? If you want to use a receiver as a pre/pro and add external amps, that is certianly possible. If you want upscaling abilities along with the latest decoders for audio, I would reccomend the Yamah RX-V863, otherwise I would go for the RX-V663. You can always get a HDMI switcher if you need more HDMI inputs than 2, since I know the RX-V3800 has 4. But that receiver should have enough power for normal use.
