Just Cause 2
Running a little ahead, we can tell you that it’s in Just Cause 2 that the dual-processor Radeon HD 6870X2 enjoys the biggest advantage over the GeForce GTX 580: 83% without full-screen antialiasing and 74% with 4x MSAA. The GeForce GTX 560 SLI configuration isn’t competitive, but the results of the single Radeon HD 6870 indicate that the game engine favors AMD-based products.
Aliens vs. Predator (2010)
This is the sixth out of the seven tests we’ve seen so far in which the dual-processor Barts XT-based card is faster than the single-processor GF110-based one. CrossFireX technology works perfectly here, doubling the average frame rate.
Lost Planet 2
Lost Planet 2 prefers Nvidia-based products. Comparing the single Radeon HD 6870 with the PowerColor Radeon HD 6870X2, we can see that CrossFireX is only 67-73% efficient in this game, the second worst result in this test session.
StarCraft II: Wings of Liberty
Here is the worst test for CrossFireX. AMD-based graphics cards still have problems with full-screen antialiasing in this game hence the low performance. With FSAA turned off, the PowerColor Radeon HD 6870X2 is quite competitive to the GeForce GTX 580.
