Let me help you understand what I mean.

SLI scaling in crysis is 85%. But in metro it is 64%.
CF scaling in crysis is 77%. But in metro it is 80%

By scaling I mean how much extra performance is gained by adding 100% extra (one more) graphics cards. SLI is unusually bad in metro. This explains why reviewers are complaining about GTX 590 performing well in some games, but bad in others like metro. The SLI scaling is bad.

Look at the anandtech numbers yourself. GTX 580 beats 6970 in metro. But when you SLI it, it loses.

CONCLUSION: SLI SCALING = BAD IN METRO AND STALKER
