iMac 2011 27" gpu downgrade

Hello everyone

I am an owner of imac 27 2011 with dead 6970m 1gb gpu.

I am wondering is it possible to replace this gpu with gpu from lower imac models?

E.g. 6750m or 6770m. Or even 5750/5670/4670 from 2010 imac or 4850 gf9400/gt120/gt130 imac 2009?

Because spent $300 for an other used 6970 gpu looks not very good idea as for me. Especially I am not needed in 3d graphics.

回答此问题 我也有这个问题

这是一个好问题吗?

Hi there. I am in the same situation with the 27" i7 2011 iMac with a dead GPU. I have access to a Radeon HD4850 from a 2009 iMac i7. Would that work?

This was a know issue on this machine and subject of an Apple recall (which has now expired).
