The readout noise of the Nikon and Canon CMOS detectors is very
similar. The high ISO sensitivity displayed by Nikon is for the
marketing: Nikon D3 CMOS (and also the CMOS D300 CMOS - Sony origin)
is a very high quality sensor, but in the end, Nikon just rises now
to the level of Canon technology."

So, if Canon has implemented a more aggressive noise-reduction
(fortunately NOT) like Nikon, the 40D may very well have the same
performance as the D3? Ho, ho, ho....

Which the 40D obviously not has, no matter how much you work with NR, so something is probably not right.

In this analysis the D3 tops every quality parameter regarding quantum efficiency, light collecting ability, etc. Also interesting to note is that the D300 seems to be a 1/3 stop more sensitive than the 40D, it has been the other way around before.
