Of course it's a bit better, but not much better.
With the best lens they've tested, DXO only give the D800 a 5% (linear)
"perceptual" resolution advantage over the 24mp D3x.
That's measurable in the lab, but you'd never see it in the field or in
print.

Meanwhile, there seem to be rumours of 50, 60, 70mp Fx sensors "coming
soon. I don't believe it:

Lenses are quite the spatial frequency filter somewhere above 20 or so
Mpix on a full frame sensor.

Sensors heading off to 50+Mpix for FF is like camera phones with 10 Mpix
and more... completely useless.
