Normally, it can be hard to envision the contrast between sensor sizing simply by checking a spec sheet. The visual underneath may offer you a stronger sense of the sensor dimensions in the D80 and K20D.

Clearly, both of the cameras have the same sensor dimensions albeit not the same megapixels. You should expect the Pentax K20D to resolve extra detail with its extra 5 Megapixels. Higher resolution will also let you crop pictures a bit more aggressively. The older D80 is going to be disadvantaged in sensor technology.
