Performance in Simulators
F1 2010 is the hottest test of this review in terms of competition. Our runners are very close to each other at first, so it's hard to make out the winner. It is only at 2560x1600 that the ASUS Radeon HD 6990+6970 configuration leaves Nvidia's products behind. Take note that the 3-way CrossFireX tandem is not much different from the single ASUS EAH6990/3DI4S/4GD5 in this test.
Performance in Strategies
StarCraft II: Wings of Liberty
Alas, StarCraft II: Wings of Liberty cannot make good use of the tremendous potential of the Antilles+Cayman pair. The 3-way CrossFireX tandem is a mere 8% ahead of the single ASUS EAH6990/3DI4S/4GD5. You can achieve the same performance boost by simply overclocking the latter. So, there is no significant difference between the dual- and triple-chip solutions from AMD in this game. It's even funnier with Nvidia's products: we've got three different Nvidia-based graphics subsystems delivering the same performance!
Total War: Shogun 2
A patch has been recently released for this game, adding to its graphics engine features. It hasn’t affected the speed of the game much, though. Developed within the framework of AMD’s Gaming Evolved program, Total War: Shogun 2 naturally prefers AMD-based products. The 3-way CrossFireX tandem is the leader of this test but its advantage over the other cards shrinks as we switch to higher display resolutions. The 3-way GeForce GTX 570 SLI fails due to poor support on the side of the graphics driver.
