I had hte 6870 before the dual 580's. The difference is like night and day. The 6870 can play on medium-high, the 580 is everything maxed, 16x aa, no ao or dof. However I freaking LOVE eye candy. so it's a bit of a factor for me. I do all the stuff, but i love it to look freaking amazing while i'm doing it. A lot of people get eye candy at first, then it fades with content. Not me, I love both equally.
