No there is not 1.5 stops less light than FX, its just like cropping the same shot to DX format on the computer

I shoot a mixture of FX & DX on a D700 when shooting events, & the low light performance is just the same at any given ISO

Again, I respectfully disagree. If you make a 24x36 print of a picture that you took with your D700 at 6400 ISO in DX mode and then make a 24x36 print of a picture that you took with your D700 at 6400 ISO in FX mode, you will see that the noise in the DX print will be more visible, thus, you cannot say that the low light performance is "just the same at any given ISO".

Hold on, you've just thrown in an extra variable, and that's enlargement, thereby putting the DX crop mode at a disadvantage. Trevor never talked about that.

Exactly, he also said "visible". The noise in both is EXACTLY the same. If you crop a FX pic to DX in computer, it is the same picture, the low light performance does NOT change after the picture was taken. It is correct that the nose will be more visible, but the noise doesn't increase after capture.
