I just upgraded from a 7D to a 5DIII myself, and can say that it's definitely worth the upgrade! I recently shot a street festival, but forgot my external flash. With my 7D, after the sun went down I would have just put the camera away as I wouldn't have been able to get a "clean" enough shot in the low light conditions. This was one of my first times venturing out with the 5DIII, and I was pretty blown away by the images I was able to get. I'm attaching one of the photos. f/4.5, 1/80, ISO: 12,800. The high ISO and relatively low noise is incredible. I cleaned it up a bit in Photoshop, but honestly it was only some light noise reduction as I do that to most images above ISO 1600 as a force of habit.
The only thing I'll disagree with the other posters on is the macro portion. I don't know why anyone would use a FF over a crop sensor when you're doing macro photography. Unless your crop camera isn't even in the same ballpark as your FF, using a crop sensor for macro is a no brainer. I still use my 7D for macro work with my 100mm lens. Yeah, macro photos still look great on my 5DIII, but the extra 60mm I get from the 7D is worth keeping it around.
