new 21.5 iMac's GPU freqs

Hey guys!
As you know, 650m in rMBPs is pretty overclocked, so I'd like to know if the GPUs of the new iMacs have non-standard freqs as well. So I'm asking those lucky ones already having new iMacs to check their GPUs freqs and post them here.
Thanks.

Come on, guys! Noone enterested in such a thing?

The easiest way is to use GPU-Z under Bootcamp. I actually don't know if there are similar tools for Mac OS X.

I actually haven't met one for Mac OS X. I'm planning to buy an iMac, last two years with a PC (after my 2009 mbp died) were pretty annoying =(

I did have not installed windows. So it needs to be an osx program

Give me some time to find an app that can do this.
