Hey Guys, So I've had this card for a few months for gaming in Windows. However everything is crashing. Games wise, in Windows. All gravy in OS X (but then I don't do anything that would push it in OS X). I recently re installed Windows, so all drivers are up to date and apart from BF3, Black Op's 2 and Deus EX theres nothing on there. I'm basically trying to figure out whether theres a power issue or something before I look at returning it. I know they'll be iffy when I'm sure it's theres a hardware fault with the card, and when they ask about the rest of my hardware I say it's a mac blah blah blah blah... I've seen a few other PC related posts about people getting some dodgy cards. If other people are using the card in theirs mac's ok then I can be fairly sure it's the card. I have a MP 3.1 2.8 Quad core. Thanks!
