Performance in Third-Person 3D Shooters
Just Cause 2
We can see some dramatic competition here. While the Radeon HD 6970 is inferior to every other graphics card and the single ASUS EAH6990/3DI4S/4GD5 makes a draw with its direct rival, the tandem of the mentioned cards comes out the absolute winner of this test.
Lost Planet 2
Lost Planet 2 has very high system requirements, so the Radeon HD 6970 is downright slow in this game. The dual-GPU card from ASUS is the only AMD-based product to deliver a comfortable frame rate. The 3-way CrossFireX tandem improves the frame rate further, yet Nvidia's solutions are overall preferable in this test.
Performance in RPG
Dragon Age II
Released earlier this year, Dragon Age II is quite a resource-consuming application, but every graphics solution included into this test session copes with it well enough. You can note that the game engine and the graphics card drivers do not yet work well together when it comes to distributing the total load among three GPUs, so we don’t see the expected performance boost on the 3-way configurations.
Mass Effect 2
We enforced full-screen antialiasing using the method described in our special Mass Effect 2 review.
Mass Effect 2 runs very fast on modern graphics subsystems, every multi-GPU configuration delivering well over 100 fps.
