DX/FX sharpness: is there a real difference? (and other DX-FX questions)

Hi all!

I've been itching to go to FX after reading many enthusiastic reviews of the D610, but I'm having a hard time justifying it...! I might just have GAS again, even though I just bought a SB-910 but HEY - it's my birthday! I read about the differences FX can make on IQ - better bokeh, low noise, better DR... I also came accross the DXO site and comparing the 24-120 (which I have my eye on, should I make the move), I see it scores so much better on a FX than a DX! I must admit, I'm a bit of a pixel-peeper and I like my pictures very sharp. Is sharpness that much better on FX? How are these tests done, really?

I'm currently using a D7000. I'm not especially into wildlife or sports, I shoot just about everything, mostly family/friends meetings, kids, travel photography, and some macro. My D7000 does the job, I don't feel limited in anything but I would like a more precise and fast AF (been struggling with AF fine tune on many of my lenses, but the body might not be the one to blame here). What should I expect by moving to FX, really? Would AF improve? I know the AF zone on the D610 is a bit limited and that scares me, to be honest. But if the AF is more precise than the D7000, that would still be a plus!

And finally, with the low prices on the D600 - is it crazy to consider it? Is the dust/oil issue so annoying, considering I rarely shoot low apertures? Could more recent units be better?

Thanks in advance!
