haha nice! I've always had Boston for computer audio, and I've never been disappointed. I think they just make good stuff!
I'd be more inclined to go for a 5 channel if I were sure of the setup I'm looking for. Having one would pretty much lock me into one setup, whereas if I were to run two amps, I'd have more flexibility to switch it up if I so choose. And from what I've read rear speakers aren't really even necessary if everything else is amped.
It's probably gonna be a case of stop thinking about it and just do it, and I'll probably be happy with whatever I choose.
