Well I got my hands on a Canon 5D Mark III camera today 😀 So the first thing I did was fire out a few photographs in ISO 8000 to see what this bad boy is truly capable of. I have embedded 1024px wide photographs but in the title above each photo is a link to see the full size photo to compare.
Photograph details: 5D Mark III, Canon 135mm Lens, ISO 8000, f/2.0, 1/400

Raw format ~ Converted to a DNG file and then exported as a jpeg:
