I think that is pretty damn good for 6400.
I never, ever toot my own horn, but yea, I think so too... I figure out of about 300-400 shots I get a few good ones... 
It seems like I don't miss focus as much with the 1D3 than the 7D. I used the exact same lens that I used with the 7D (85 1.8). And someone in another forum said it's better to get the exposure right in camera, that way noise reduction is less or not done at all, so that's what I focused on that night. And for 80% of the keepers I just did a little sharpening and left the noise as-is, as was with the one I posted.
Still almost makes me wish I had a 1DIV!!!
