you might wanna get additional cooling before doing that. afaik nvidia drivers support oc.

I think the original poster means that in the article it's stated that the 15" uses the same hardware as the 17" (except the size of the screen) but the 17" GPU and GPU memory is clocked at a higher speed.
The cooling is the same on both, so the 15" would just run as hot as the 17" if they were clocked to the same speed.

It depends on how the GPU speed is controlled. It could be pin setting or signal applied by a support chip to the GPU. Or it could be software based configuration through OSX/EFI.

If it's the latter there could be a patch (OSX) or a firmware update (EFI) that could do the job.

In theory the smaller resolution could allow GPU to achieve better performance if clocked at the same speed as the 17".

Interesting comment about the nVidia drivers. Although there are drivers (almost certainally created by nVidia) they aren't supplied seperately from OSX (ie there's no download from nVidia themselves).

At a guess there's more air flow through the 17" casing than the 15" which allows the GPU to run warmer.

Anyone tried ATITool in Bootcamp?

Don't try this without a good cooling pad at the very least.
