Upgrade the GT120m GPU to 5750m from 27" iMac
I currently have a 2.93 Ghz C2D early 2009 iMac with a GT120m GPU. Recently it has stopped working as well and is due for an upgrade/replacement. I know that the GT130m and 4850m will work with no problems, but would the 5750 from the 27" iMac also work. They both use the same MXM 3.0 Type B socket and the 5750 (which is actually a 5850m) has a lower TDP than the 4850. This would mean that I should have no problems physically installing the card, and it wouldn't overheat the computer. Software wise would this setup work? The GPU is indeed an Apple version and has appropriate drivers.
Is this a good question?
