Buying an older Mac Pro for VW - false economy? in General Discussion Posted April 14, 2016 · Edited April 14, 2016 by col37400 Ok. I think my question is answered! Thank you. One other question, looking at iMacs including refurbed ones in the apple store - it seems that you can knock a few hundred pounds off with a lower spec graphics card - say, NVIDIA GeForce GT 750M graphics processor with 1GB of GDDR5 memory or NVIDIA GeForce GTX 775M graphics processor with 2GB of GDDR5 memory in place of AMD Radeon R9 M290 graphics processor with 2GB of GDDR5 memory I see in the VW knowledgebase articles that it's mentioned the GeForce ones with "M" suffix are laptop type ones and less powerful, so it's probably worth paying the extra for the GeForce option?
