Actually now that ive been thinking about it....Is it worth going to the 7300 if im not gonna use the video upconversion?(Yes I know the 635 has it also but not as good I dont think)

I heard the 635 has Logic 7 that can be layered over dolby but this is only going to be a 5.1 setup so would that matter?

I can get the 7300 brand new for $1250 which is double what the 635 is. Worth the extra money or should I put it towards a amp for the fronts?

Also anyone thats heard both does the 7300 sound any better?
