I figure that nVidia has extracted every last ounce of performance of my 2 GTX 460 1GB in SLI but I'm playing a new game (for me, anyways); Metro 2033 and I swear that my overclocked cards no longer crash running this game at 870/1740/4000 at 1.005 volts. Performace seems to be a tad better, too. nVidia: way to go!
