The Guru of 3D posted a comparison review between GeForce 9800 GT and GeForce 660 GTX

A short while ago the EU press was on a conference call with NVIDIA regarding the GeForce GTX 660 launch. In that call the press was briefed about the new GK106 based GPU. What was a little strange to see is that in that presentation the good old GeForce 9800 GT reared its head in some benchmark examples.

Last week I got a call from NVIDIA explaining why that was ... a lot of the demographics show that end-users who purchased their PC a couple of years ago very likely still have a GeForce 9800 GT. NVIDIA's demographics show that lots and lots of people are still using that card (and apparently it is a lot of them) are bound to upgrade, and the most logical step is the GeForce GTX 660.

With that mindset NVIDIA asked us if we'd be interested in doing a little article on the two products. Sure why not, it's something different for a change and the thesis makes sense. Most of all it will be interesting to see how a four year old card and the latest one from the mainstream segment perform.
