These things used to excite me more, but lately I’m just interested in using what I have.  However, I’m sure this type of information is still valuable to a lot of people.  DigitalCameraInfo.com has a comparison of the two cameras.

At under $3,000 (now), the 5D offers image quality comparable to the 1Ds Mark II and D2X at a high-end consumer price point. Conversely, providing much of the 5D’s image quality in a far more favorable design, the D200, at well under $2,000, should be viewed as a breakthrough product in its own right.
