I now have two of these in SLI.
$140 is a good value, and it's definitely worth $125.
I don't play any of the games you listed but (when I was running a single 560) Crysis 2 with high-res texture pack played smoothly on "very high". "Extreme" was playable. "Ultra" was annoying. (This is on a 1680X1050 monitor)
With two in SLI now, it's cutting through Crysis 2 on ultra everything like a hot knife through melted butter.
Thats great news. Its safe to assume they outperform the 6850 and 7770 then? Also know anything about the galaxy brand? Theres a zotac one going for 149 with free ship on amazon. I would get that if it means zotac is a better quality card
