Performance in Third-Person 3D Shooters
Just Cause 2
This game’s integrated benchmark does not report the bottom frame rate.
Combining a Radeon HD 5970 with a Radeon HD 5870 into a single graphics subsystem makes sense here. This is the only graphics subsystem to make the game playable at 2560x1600, its bottom speed being always higher than 25 fps. The single Radeon HD 5970 is close to that result, yet the gameplay is smoother on the Radeon HD 5800 3-way CrossFire.
Resident Evil 5
Once again we can see no practical benefits from using a Radeon HD 5970 together with a Radeon HD 5870 in CrossFire mode. This configuration has the same bottom speed as the single Radeon HD 5970. The game having modest system requirements, there is no real need for a top-performance multi-GPU solution.
Street Fighter IV
The integrated benchmark does not report the bottom frame rate.
Top-end multi-GPU configurations are not called for in this game, either. The frame rate is over 200 fps in each mode. The Radeon HD 5800 3-way CrossFire and the GeForce GTX 480 SLI seem to hit the ceiling set by the game engine and the capabilities of the testbed’s CPU.
