That receiver will be with you a LOONG time.
Regardless, make sure it has HDMI switching, decodes the latest formats, and has 5.1 inputs and pre outs.
These are essentials, the rest are "features".
If you can afford it(and find it) an Integra (made by onkyo) would nor cost much more and have way better quality, they tend to pay more attention to those.
But if you are not interested go for the 806, its a huge step up for a few hundred more bucks.
Remember its gonna be the hub of your system, after all.

I was recently in your shoes. I bought an Onkyo 905 off the bay right before the new models came out. If you can live with less gimmcrackery I'd suggest getting a "new old stock" 805 or 875. More power less money.
E.T., go with the 806. Its reasonably price if you buy it off the net. And seeing that your going to use it for movies,TV and gaming mostly, I dont think that you will get any significant benefit by going with a higher end receiver. The Onkyo's are excellent for the price. Finding a new 805 is an option. Save the money and buy a nice Blu-Ray or subwoofer.
