Hi, I'm a total noob when it comes to this, but I'm looking to get a GTX-280 to run on my mac pro 2008 which is running win XP. I hear it's just a case of getting some new cables and throwing it in there, but also some people are concerned about heating issues..? Have any of you installed this card successfully and has there been any issues with it? It'd be good to hear which method you chose as well, I've also seen this -> http://forums.macrumors.com/showthread.php?p=4821315#post4821315 which maybe applies more to older mac pros. Thanks.
