Does it seem like apple may allow for a gpu upgrade for the Imac 27" in the future? lets say if the new revision comes out with a ATI 5xxx with the same slot design, I would think you could upgrade it? Ifixit has photos of the removal of the gpu card. http://s2.guide-images.ifixit.com/igi/6cGAVgAwJpKFM5Ew.large http://s2.guide-images.ifixit.com/igi/DuvQipquFYmSvGs3.large http://s2.guide-images.ifixit.com/igi/aVSHuUxm3d5ZLJPN.large It's definitely not soldered to the motherboard like all other imacs. I was also wondering if the i7 cpu is socketed. Some people said they were, but i've never seen photos of it.
