HI I have a MacPro Early 2009 with a os x flashed Nvidia GTX 570. I'm running latest version of Yosemite. Just want to confirm if possible that I can install this card with Yosemite and it'll work. I realize I may need to download some drivers but i'm not that interested if it's going to be a major hassle to get it to work (modifying text docs,etc...). Anyone have any thoughts?
