Hi everyone,
Which GPUs can you use as upgrades for this 2010 model? Mine has a Radeon 5670 512mb and I'd like something a bit more powerful...
Thanks!

lucky, i have a 256 mb card
Heh. I just replaced the 512mb 5670 card with the 256mb 4670 card.
Why, you might ask? Because of Mojave support. The 4670 is supported under Mojave but the 5670 is not…
One question:
i can put this GPU: NVIDIA GeForce GTX460M
on my iMac Mid 2011?
or i will have problems with the Drivers?
Wonderful guide! First time I opened a imac.
I need to replace the LCD cable connector on the motherboard. It is broken and it caused a short circuit on the motherboard. On the motherboard, underneath the grafic card, I've found a fried SMD inductance (L9000 on the motherboard) in the powerline of the grafic card. I restored the powerline with some solder leaving the inductance out. Should be no problem.
