The games we tested fall into two general camps. Arkham City, DiRT 3, and Serious Sam: BFE are all absolutely playable on the GTX 680 or 7970 in a single-card configuration, even with detail settings turned all the way up. Shogun 2, Metro 2033, and Crysis 3 aren't. In Shogun 2 and Metro 2033, however, the Titan maintains a playable frame rate at High Detail when the other two cards are stumbling and stuttering. Crysis 3 was the one exception -- in that game, all three cards remained playable at High Detail, and dropped below that mark once we increased to Very High Detail and added 4x SMAA. Pe
