Hi guys I have been totally off the game for a long while hardware wise (since buying my 2009 Mac Pro I haven't needed to think about it ) I got the 2009 Mac Pro with the Radeon gfx card (4870 was it?) and only about now am I noticing it not really keep up with the modern games (sure I could turn a few settings down, but I dont want to ) So what is the best OSX supported gfx card I can buy for it? Is it that Geforce 285 that came out not long after the 2009 launch? Or is there something better now? I would prefer a card that is supported out of the box by OSX, but am open to something that requires a little hackery to make work too. I just wanna breathe new life into for another couple of years gaming wise (especially now I can play TF2 etc via Steam ) before I replace the machine late 2012 / early 2013. Thanks guys!
