Hi all, Recently posted about graph cards here http://forums.macrumors.com/showthread.php?p=18056075#post18056075 awhile back and right before Mavericks came out. Which at that time I was not even aware was a thing. So recently I started looking around google and didn't have much luck finding the changes between Mountain Lion and Mavericks in terms of graphics card supports for the mac pro systems. I'm running the Mac Pro 3.1 and am probably going to upgrade the card this holiday season. Does anyone have any insight on this? Thanks in advance.
