What is your D700 -> D800 experience?

I am only taking family photos.

I changed from D300 -> D700, I felt so much happier.

The D700 is good, as we know.

If you have changed from D700 -> D800, What is your experience?
Do you recommend that?

Is D700-> D800 a better upgrading experience than D300-> D700?

I am after better high ISO performance.

Some D800 owner said the high ISO is only marginally better than D700 "natively".

If so, then I should wait for the next better camera, but D800 successor may be years away.

(Of course, D700 is adequate enough for family photos now.)

No, I don't want to convert the 36MP to 12MP all the time.

Do I need more megapixels? I don't print much.

I think it does allow me to crop to compensate for some lack of framing techniques.

Sometimes, I take group shots, and do appreciate the ability to enlarge each face.

Thanks for your comments and opinion.
