Is it worth the upgrade?

I am looking at the fallowing Yamaha receivers which will either power my Energy CF-70's or Infinity p263's.

I know the 671 has a little more power but I do not understand a couple specs it has over the 571. According to the chart below, the 671 is the only one that has a Rated Output Power (20Hz-20kHz, 2ch driven) which is 90 watts. The 571 doesn't have that spec.

Really my only question would be, if I don't need networking on my receiver, is there any major reason why I would go with the 671 over the 571? Will the extra wattage make that much of a difference? Also, if I only plan on using 5 channels, is there any reason to go with the 571 over the 471?

Thank you.

Ignore the 471/571/671, and get this instead:

Damn, thanks for the heads up. I am a noob when it comes to Home Theater but on the surface, it looks just as good, if not better than what I was looking at.

May I ask you why you recommend this over the other ones I was looking at?

Went with the RX-A800.

Yeah, I'm impressed with the Yamaha RX-A AVRs.

Normally I look at the measurements of the AVRs in HTMag and quickly turn away. But when I saw the measurements of the Yamaha A1000, I was quite impressed.

Then I saw the specs and prices on Amazon for the A700 & A800, and I was really impressed.
