I have a early 2008 mac pro. I've been wanting to get a new video card for awhile. Like everybody, I've been waiting to see if any new updates happen. But, like everybody who knows when and now I'm not sure I will even get one when the come out. In the meanwhile I think I'm going to go for a new card for the mac I have. My question is, what is the difference between a GTX 570 from an internet retailer or going through MacVidCards. It looks to be about a $200 price difference. MacVidCards being the higher of the two. I'm kinda confused as to what the benefits are? The main difference I'm reading is MacVidCards will show the boot screen. Is there something I'm not comprehending that justifies the extra spend? It seems like both will work with the new drivers and what not, but before I do anything I want to make sure I make the right decision. Any insight is appreciated. Thanks.
