Just bought a GTX 960 for my mac pro 2009 - hopefully the Nvidia drivers will be stable on that.On Bootcamp, downloading the Nvidia driver for Windows made a big difference, and is completely stable. Unfortunately the Nvidia drivers don't appear to be very stable with the bespoke GT 650M in the MBPr .Install Windows 8.1 on a Mac Book Air no DVD drive How to install Windows 8.1 on a Mac running OS X Mavericks How to install Windows 8 on a Mac with Boot Camp Easy Version General Boot Camp questions about installing Windows 8 on a Mac The list above should be up to date.

But the instability is annoying with the GT650m - its not down to temp - it stays around 65-70 degs .I decided to try and squeeze some more power out of the 650M by downloading NVidia's display driver, rather than using the OS X version.Driver installed fine and appeared to detect the 650M. If it helps, I was running an outdated version of El Capitan from October (I've been in a place with *really* bad internet), and I just updated to 10.11.5 today.
