Notebookcheck added the m295x to their rankings list. It performed above the 780m gtx in the 2013 iMac, but below the newer 970m gtx from NVIDIA. http://www.notebookcheck.net/AMD-Radeon-R9-M295X.129043.0.html It would appear the AMD card is a downgrade versus continuing with the x80m gtx series. I was hoping to see them on par with one another. Maybe as more benchmarks and data rolls in the gap will narrow.
