iMac graphics card upgrade

I have a 27 inch iMac mid 2010, running High Sierra. I’d love to upgrade to be able to use a more recent OS, but I need to change the ATI Radeon graphics card. Is there anyone who can advise me which would be the best upgrade? I love my iMac and I’d rather upgrade than try and sell it(not give it away).

iMac 27″, macOS 10.13

The GPU in iMacs are not post sales upgradeable, by user, or by Apple.

iMac graphics card upgrade? Heyo! I recently bought my first iMac! Its a 2010 imac, 27", core i7-870, 12gb RAM, and a Radeon HD 5750. Ive already upgraded to an SSD, which got me thinking on other possible upgrades. Is it even possible to upgrade the graphics card in this machine? I think it would go well with a GTX 1050, but would it even work? Thanks for any help you can give!
