Performance in Third-Person 3D Shooters
Just Cause 2
This game’s integrated benchmark does not report the bottom frame rate.
Like in our previous review, Nvidia’s architecture shows its best at high resolutions, enjoying a large lead over the AMD solutions, but also having a lower bottom speed. Subjectively, it seems that the Radeon HD 5970 offers smoother gameplay at 2560x1600. Using two discrete Radeon HD 5870 cards for playing this game does not make sense as they do not bring any performance benefits.
Resident Evil 5
The Nvidia SLI technology does not work correctly in this game with the GeForce 257.15 beta driver. It is only at 2560x1600 that we can see a performance growth relative to the single graphics card. However, there is no difference between the GeForce GTX 470 and 480 there. There is also no difference between the Radeon HD 5970 and the pair of discrete Radeon HD 5870 cards.
Street Fighter IV
The integrated benchmark does not report the bottom frame rate.
The colossal resources of modern multi-GPU solutions are not called for in this game, so the GeForce GTX 480 SLI only goes ahead of the 470 SLI at 2560x1600, which can make no difference since both deliver an average frame rate of over 200 fps. There is no difference at all between the AMD solutions but, as we said above, this must be due to the Radeon HD 5970 having a dedicated PCI Express switch. This may also be the result of some software optimizations targeted at this specific graphics card.
