So... I purchased this (supposed to be) GTX285 "for mac" because it has two dual DVI outputs, something I need. I received a black/red card "Asus Matrix" with the extra power cables, etc.. -- what is this? A flashed PC card, or?... a scam? Seller hasn't replied my email yet, but it is a reputable eBay store, with thousands of positive feedbacks, 100%. I did not install this card, I'm afraid it could ruin my 2010 quad. Any advice? I need two dual DVI outputs.
