I'm a bit confused about this. I stumbled upon two different models of the 5870 manufactured by XFX. They're both the same price and have the same specs. If they're both the same, why would XFX bother manufacturing a second version of the 5870? I'm aware that they have redesigned earlier models of their 5870 cards where they repositioned their fans to the center of the card instead of putting them on the right end side. I'm wondering if there's a difference between these two cards. (Disregard anything related to purchasing either one of the cards, I just want to know if there's actually a difference between this two cards)
