A friend's workplace is looking to upgrade the GPU in one of the PCs to improve performance for Revit. It currently uses an old Quadro which is struggling, while another PC of the same model but upgraded to the Quadro K2200 does a much better job. So they asked my friend if there's anything better than the K2200 for under £500. No preference between Nvidia and AMD as long as it helps with Revit. I suggested looking at the M2000 but I have no idea if there's anything better.
