With the updated electronics, larger CMOS sensor and larger pixels,
it is not that big a surprise that the D3 can achieve another stop
high ISO advantage over the 1D3 and 5D. Its other ISO speeds, 12800
and 25600, are really there for marketing reasons.

There are several D3 images in this thread that were taken beyond ISO 6400 that I think are usable for many purposes. Maybe not for yours, but certainly for others:

I wish Canon let us adjust the ISO between ISO 3200 and 6400. It's as if they added "H" for marketing purposes.
