Imac 24in, upgrade possible?

[Caseynd]

I have an Imac 24in that I purchased last June with the upgraded video card, NVIDIA GEFORCE 8800 GS W/512MB. Anyone know if it might be possible to upgrade it to one of the newer cards just released with the new imacs?

The iMacs use laptop parts. This really isn't possible.
