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?
