F1 2010

As a rule, multi-GPU technologies do not work effectively, if they work at all, in new games. But in the released F1 2010 CrossFireX technology is 97% efficient in the FSAA mode. Its efficiency drops to 43% in the FSAA-less mode, though. As for SLI technology, the GeForce GTX 460 tandem is 58 to 70% faster than the single card.

NBA 2K11

Multi-GPU technologies do not work at all in this new game. Well, NBA 2K11 doesn’t really need CrossFireX or SLI because the single cards deliver playable frame rates even at the highest resolution with FSAA. You don’t need more than one card to play basketball.

The two pairs of Radeon cards boast 100% efficiency of CrossFireX technology compared to the respective single cards (by the way, that's a tenth game in which they perform like that). Nvidia’s SLI technology is not so effective, yet the GeForce GTX 460 easily maintains its lead both when single and as the SLI configuration. Overclocking the Radeon HD 6850 to the frequencies of the Radeon HD 6870 reduces the gap between them from 13-17% to 3-5%.
