AMD Radeon HD 6750M 512 MB hardware upgrade

What video card is compatible to replace the AMD Radeon HD 6750M 512 MB in iMacs 21.5" mid 2011? I could not find on the internet any model that has more memory and is compatible with this iMac model.

Is there a list of compatible parts on the Apple website? What's the link? Where to buy?

Were you asking because you're trying to increase performance in general?

First, consider upgrading your RAM. 4GB is really on the low side. I've upgraded my MacBook Pro (Early 2011) just a few minutes ago and found your question as I was also curious if the nVidia onboard memory was upgradeable.

Second, you should consider a solid state drive. The 2.5 GHz iMac 12,1 takes up to 500GB, but the 2.7 GHz takes up to 1TB.
