Nikey22 for the win!
The macrumors forum has been updated, there is a vbios available to flash the nvidia k4100m to work with the 2011 imac for a gpu upgrade. Now, the 27 inch iMac is going to be the best option here, because the k4100m is a more powerful card that has a tbp of around 100watts, which is similar to the radeon 6970m that shipped in only the 27inch iMac.
Best for the 27 inch iMac, because it has a power draw of 100w
Page 288… but there is a link to the bios within the Mac rumors main page.

Running about $89 on eBay at the moment, which isn’t too bad of a price.
