Gains in 1920x1200
We put the performance gains from tests into graph form so that they could be interpreted more clearly. If there are no results, this means that the multi-GPU system had a bug that made the game unplayable. A gain of 0% indicates either that there is no gain or that it reduced performances and in this case would be deactivated by the gamer. Therefore there are no negative results. Note that triple SLI gains should be compared to those of GeForce 8800 Ultra SLI and not 8800 GT SLI because they are less limited by the CPU and have more room to express their potential.
8800 GT SLI and CrossFire gains are generally similar and each has a small advantage depending on the game. Gains were lower with the GeForce 8800 Ultras given that they were more often CPU limited. Triple SLI was of little interest here.
With antialiasing 4x activated, the load on the graphic system increases and this in theory allows all the solutions to better express their potential. All showed higher gains except the Radeon HD 3870s. For some unknown reason, the poor performances with this filter seem amplified in CrossFire. Finally, triple SLI is likewise of little interest here.
With DirectX 10 game, triple SLI makes its presence felt while CrossFire is behind due to a reduced gain in Crysis.
CrossFire bounces back in DirectX 10 and with FSAA 4x showing rather consistent and large gains in the three games tested.
