6600 AGP overclocks

[AltTabbins]

I was looking at a basic solution for a little gaming on an extra pc. I would like to get a 6600gt, but was looking at the 6600 256mb. Both chips are made with the same process, so does that mean I can easily overclock a 6600 to gt speeds?

Anybody done this?

Most of the 6600's (non GT) have pretty slow ram that has little to no room for overclocking.

Not sure how well the core could overclock though.
