I’d like to know how much graphic memory is on the replacement graphic card you have listed for the 27 inch, mid-2011 iMac. Thanks, Dan
There are three versions of GPU boards this series had: AMD Radeon 6770 with 512 GB - 661-5967AMD Radeon 6970 with 1 TB - 661-5968AMD Radeon 6970 with 2 TB - 661-5969 You’ll need to ID which board you had a question on by linking the part number I’ve given you here to the part listing. There are a few other MXM boards that could be used but you need one with the Apple firmware to work properly.
