It works, BUT…
A serious but, depending on your skills and claim.
- You cannot install it without modifying the cooler
- you have a black screen until the software installs the drivers
- you have no brightness controls
and some things more.
But it works and is really fast compared to the old AMD
One additional comment, to end this discussion. At least from my point of view.
Is it worth the hassle?
NO, ABSOLUTLY NOT.
All of you are trying to keep a Zombie alive. But a Zombie is already dead!
I purchased a 2019 iMac because my 2011 "kept dying" on every aspect of its "Life". Yes it is sad and it is a shame. Thats my opinion, too.
First I wasn't willing to accept it, which was the reason to repair it over and over again. And to live with this really annoying quirks. Also I’m absolutely sure that it is possible to use old computers like the 2011 iMac. It was an great machine and in theory is still if its working.
But it is also an ill-fated thing, plagued by some faults with IMHO with no good or even acceptable solution.
I wouldn’t recommend to anybody who is not a Mac fanatic to do this.
Let it go and buy something (much) newer.
As a normal Mac user like I’m. Your "hobby" is doing things with your Mac. Not working on constantly to keep it running.
Update: the project was too impractical and expensive, I ended up building a budget pc and bought a displayport to mini displayport cable, now I use the iMac as a monitor. May change it in the future given that it is pretty power-hungry solution for a monitor.

You could use up to a 780 mxm, but I would also max out the ram and add a pair of SSD's in raid zero... you will require an 18'' Sata cable for the second connection of your SSD's.
