Here's an old test I did with the 40D: http://philhart.com/content/astropho...xposure-length
It's hard to tell the difference between any ISO setting once you process them! I know this is true for the 5DMKII as well. Very little to gain going above ISO1600/3200 when shooting RAW, but a lot to lose in dynamic range IMO.

I took a sample ISO3200 and ISO 6400 and ISO 12800 the other night as you suggested. I'll post them soon.
Yes I am mindful of that dynamic range curve of these DSLRs where the higher the ISO the worse the dynamic range. There must be a sweet spot though and in my use so far I would estimate that to be ISO6400 on this camera. But looking at the tests I might be surprised. ISO3200 seems a sweet spot for 5D2 judging by posted images.
