Hi all,
i work on a pimped-up MacPro that came with "just" a non-EFI MSI 970 GTX and no standard videocard.

Eventually i need to upgrade from El Capitan to Sierra because newer versions of some apps i use need at least 10.12 and i would need to know if default 10.12.16 OSX drivers will support my videocard, just for the time needed to download and install Nvidia web drivers.

For download and installation i might also use the flashed 680 GTX i have on the other MacPro (that is going to keep 10.11.x for retro compatibility with other apps i use)

Would any of you help me not to suffer a potentially deadly shock having to deal again with a black screen?
:)
