upconversion and streaming w/ separates?

[got rice]

I am going to eventually upgrade my receiver. I was considering the denon 3808, yamaha3800 and the onkyo 875/906, but after reading some threads I'm considering this for example: Yamaha 663 with emo, outlaw,or rotel amp.

I do have a couple questions though. First how is the upconversion on the Yamaha 663, I understand the Yamaha 3800 uses the anchor bay chip. Are they comparable? The Onkyo's Reon H?? upconversion technology is supposed to be a much better than all three. Is there a separate pre/pro that offers the Onkyos upconversion chip?

Second, I would like to stream music from my laptop. This is another reason I chose the AVR's listed above. If I go with separates, will I be able to find a separate non amplifed prepro that would satisfy these requirements?

With this in mind I understand the Yamaha 663 doesn't stream.
