I just like the top one more because of how it looks, dunno what the difference between them is. Also, the top one makes my shopping cart total $15 more, including the $10 difference in price already, because
of how the combos work out.
Theyre still the same chip... kinda like how 5870 is cypress xt and 5850 is cypress pro and 5830 is cypress LE... same chip just nerfed shaders and ROPs etc. With those two cards there will be no difference apart from calling where the second link is using reference cooling and the first is using something else
