Nvidia still has to make an announcement about the subject, but the folks at German PC gaming hardware site, er, PC Games Hardware have actually managed to benchmark such a configuration. Their set of three GeForce 8800 Ultra graphics cards seems to yield a significant performance improvement over a standard two-way 8800 Ultra SLI setup, as well. In Crysis, for example, the three-way SLI doubles minimum frame rates from 7 FPS to 14 FPS and boosts average frame rates from 27.1 to 37.9 FPS. PC Games Hardware's tests also include Unreal Tournament 3, F.E.A.R., and Company of Heroes.Source: Tech Report
Across those four games, three-way SLI improves minimum frame rates by a factor of 2.5x and average frame rates by a factor of 2.4x over a single card, compared to respective factors of 2.1x and 1.9x for two-way SLI.
