Tiny-samples but look *very good* to me...
I almost had a D700 for my birthday last february. I phoned my dad up on the morning he was going to buy it for me and told him that I wasn't entirely sure about it, and to leave it.
...Don't know but... I could swear I read you called your wife or husband, instead...
I'm glad I've stuck with Canon as I am very pleasantly suprised by my 5D at higher isos, however I still feel that the ultimate high iso performance goes to the D700...It's just that my 5D gets an awful lot closer than I could have imagined!!
...You can rest assured, though, and even write on a little yellow sticky that you can match and/or surpass the D700 (or D3) output, guaranteed... and all within Canon's current lineup of equipment... maybe not with the 5D, but you certainly can do it.
Anyway I played around with pushing the 3200 shot again, and seem to have come much closer to not blowing out the whites.
Much better, indeed.
Suggestion: increase saturation on-board or in your raw converter by one notch (seems like you maybe using RIT/ZB by the noise-spectra/signature I see), and then proceed with noise reduction processing exactly as you would for your less-saturated output.
You will get better color response/saturation, almost identical noise-reduction performance.
Watch for unwanted color casts (magenta's, purple or green-like).
