FWIW I would have recommended a pre-owned 7D. They're amazing value right now in a market flooding with 7D bodies in anticipation of the upcoming 7DII.

Looks like the high ISO noise levels between the two are pretty close, at least close enough to not use that as a deciding factor in choosing one over the other. (based on this comparison between the two) Unfortunately, until CMOS (or CCD) technology changes, ALL digital sensors will have noise. What makes the biggest difference at this point is the size of the sensor and even more importantly, the size of each sensor pixel.
Honestly? I shoot all the way up to ISO 3200 without fear with my 7D. "Noise" doesn't stop me from getting the images I want. I know if a particular photo calls for some NR, I use either DPP or Lightroom 4. They both do a great job of getting rid of image noise. But again for the most part, I don't use NR much at all.
The photo I uploaded was shot with my 7D, 1/8000s, f8, ISO 2000 without flash using my 70-300L IS USM lens. No noise reduction, simply a RAW file processed using DPP. Nothing at all wrong with this photo, measured against any camera. Even in the dark areas (shadows) the color is smooth without a bunch of "hot pixels".
