Yesterday I finally got around to ordering my new graphics card. It is a MSI GeForce GTX 970 4GD5T Titanium OC card. After ordering I got curious about the web drivers. http://www.ebay.com/itm/291560857366?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT (not my ad, just what I purchased) I know it will work with the current nvidia web drivers I have installed and turned on for my current GTX 570. If for some reason the web drivers happened to go out on me, like if I updated before waiting for the web driver to get an update, would I still be able to control my mac pro with screen sharing from my macbook air? Or would I have to take my new graphics card out and put my 570 back in- which is supported by native osx drivers? I'm guessing when you have a graphics card that doesn't have native OSX driver support you have to update the nvidia web drivers first before any OSX related update beyond individual programs updating? I have automatic updates turned off in OSX, I check for updates manually. For my 2012 6-core Mac Pro.
