iMac 2011 graphics failure & upgrade

[Chow Andrew]

I have an iMac 21.5 inch 2011
Failed graphics and doesn’t have a hard drive with the os on
Is it possible for a new graphics card to be fitted in the Mac and works right out of the box?
I can’t seem to find any video prove or forum post of K1000m/K1100m/K2000m/K2100m working after being inserted in the Mac
Is the GTX 765m/770m the safest bet?

So the K2000m can just be plug into the computer with the loss of boot screen?
Without original graphics card and is drive isn’t an issue?
