I think Falk may have spoken a little quickly, leaving out some pertinent info - at low ISOs, with good lenses, at apertures where you're not trying to take advantages of the FOV/DOF control, the D700 is mostly going to be indistinguishable from a K-5 (or almost any modern aps-c camera.) But this is also true, to a large degree, for a good point & shoot. That new Nokia 41MP phone camera is going to give you brilliant images as well at base ISO, where AF isn't an issue.
When the D700 (or D800) is going to help you is when you move up from base ISO, and into a bit more demanding shooting conditions - DR will be better on the D700, as will noise. And of course if you want to take advantage of the DOF control with wide-to-mid-telephoto, it's easier on FF. (Then there's the large VF, AF performance especially with tracking and low-light accuracy, etc, but those attributes are not directly image-related, just usage advantages.)
But if you shoot at f/8, base ISO, and don't need top-line AF, the K-5 is probably just as good or better for anyone. (as would be the K-01, in those conditions
)
Check out this link - and select "D7000" (which aproximates the K-5) in the legend on the right to compare PDR to the D700:
