SX40 or SX50? A BIG difference?

I'm liking the HDR stuff.  But can you post one with NO post processing at all, to see how the OOC image looks?

Right now, I think I've decided that if I can sell my SX40, I'll maybe pick up a SX50.  All of those "little" improvements are starting to add up and make a difference to me now.  The only real downside to doing so, and it is a BIG downside, is that some folks feel that the IQ of the newer SX50 is not up to the level of the SX40.  And, for most of us, me included, the IQ is the most important part.
