I know everybody is hoping for the GTX680m to be the GPU of choice for the new high end iMac. And that the update of the new iMac line is taking so long because of availability problems caused by 28nm wafers shortages to produce this GPU.
But before you get to exited and might get disappointed when the new iMacs arive.
This GPU costs between 400 and 500 dollars/euro in desktop form.
The current 6970m used in the high end iMac is based on the desktop Radeon HD6850 which costed around 150 dollar/euro when the 2011 iMac model was released.
No way Apple is going to use such an expensive gpu in their iMac line
My guess is that Apple is waiting for the nVidia GK106 chip which hasn't been released yet.
This would also explain why the 2012 iMac model hasn't been released yet.
Even when its been over a year since the last update.
Expected release date to this GPU is this summer.
rumored performance is around twice as fast as an GK107/GT650
