No.

No.

Isn't the GPU separate from the logic board? AFAIK, it is... Or at least it was in previous models.

the upper model 27's are i think

The PCI-E Mobile Card (as I believe it is) is removable for the purpose of replacing the GPU. You could, then, upgrade...but really only to the next release of the 27" iMac, provided it uses the same connector.

It has been done, as there are vendors that sell Mac-ready GPU's, but it's definitely not supported and could be inadvertently broken by future firmware/software updates.
