As you can see by my signature, I have a very similar setup to yours. I just upgraded my Denon 910 to the 2910 and I am extremely pleased with the picture quaility. I use my system 100% for movies only so that is why I didn't feel it was necessary to spend the extra 500 bucks for the
3910. I do not have a projector,plasma, DLP or LCD... so I am not supposed to see a difference with the DVI connection. But, I don't think the 910 was that great of a machine, so it seems like huge upgrade.
My next upgrade I am thinking about is going ahead and getting the M80's and then seeing if i can locate a good deal on the 5803. Who knows if that will happen though!
Good luck with your new system.
