This is very timely as I just purchased a receiver yesterday from Costco. I ended up getting the Onkyo TX-NR6050 however. Everything I read says those two units are both very good and pretty similar (and you can still get the Denon AVR S760H online at Costco.com - it's just at the regular $499 price). There was one feature that ultimately made me choose the Onkyo over the Denon however. That is the 2nd HMDI output. The Onkyo acts as a true 6x2 matrix switcher and this is perfect for my situation. The fact that the Onkyo is also on sale right now for $399 also helped. It is suppose to be delivered next week.
I am replacing an older Integra unit that had it's HMDI board go bad. I hear the newer units don't have this same issue, and the NR6050 actually adds a fan over the HDMI board, so I am comfortable with my selection as far as that is concerned.
My current set up is 5.1, but I actually have a pair of ceiling speakers that I have never used and could easily add them in order to take advantage of the 5.1.2 capabilities of the newer receivers. The biggest hurdle will be the "wife acceptance" factor, but I don't think it will be too hard to get approved.
My room is "L" shaped and has two TVs in it. Normally the 2nd TV (32") is pointed towards an "office" area that cannot see the main TV, but it is also on a swing wall mount and can be moved over next to the main TV (65"). This is great for watching two sporting events at the same time. Because of this, normally we want both TVs to display the same show, but there are also times when we want different shows on it. The older Integra unit had a second HMDI output, although it only mirrored the main output. This worked fine, but the fact that the new Onkyo actually has two independant HDMI outputs will work even better.
