Since I started using Big Sur, Lightroom Classic was locking up and starting again. I had to discontinue use of the 2 GB graphics card because it seems I now need 4 GB to run lightroom properly instead of 2 GB. Does anyone know where I can purchase a comparable 4 GB Graphics card?
Thank you,
Jim Triplett
The 2014 5K iMacs (as with all iMacs 2012 and newer) have the GPU soldered to the motherboard. It is not upgradable.

The GPU is integrated on to the main logic board, in short it is a part of the computer and cannot be upgraded. These GPUs were from 2015 iMac's from what I can see. If you need a higher powered GPU then it's time to buy a new Mac, either that or run an earlier version of Lightroom.
Graphics AMD Radeon R9 M29OX 2 GB
