Performance in Third-Person 3D Shooters
Just Cause 2
The Radeon HD 6990 is ahead at the low resolutions but Nvidia’s solutions overtake it at 1920x1080. The GeForce GTX 580 SLI then leaves the Radeon HD 6990 behind by 15%. The advantage of the SLI tandem over the rest of the tested products is that it ensures a higher bottom speed, up to 40 fps.
Lost Planet 2
This game favors Nvidia and runs fast at 2560x1600 even on a GeForce GTX 580. Two such cards are unrivalled and beat the Radeon HD 6990 by as much as 50%! Of course, the GeForce GTX 580 SLI tandem is going to be more expensive than any dual-processor card but it offers unprecedented performance for that money. We guess there are enthusiasts who will be willing to pay $1000 for such a high speed.
Performance in RPG
Dragon Age II
We use a patch with high-res textures and FSAA.
Dragon Age II was used in AMD’s marketing materials and for a good reason. The Radeon HD 6990 is invincible in this test. The GeForce GTX 580 SLI tandem is the only Nvidia-based solution to deliver full comfort at 2560x1600, but it is 32-33% slower than the AMD-based flagship at 2560x1600 and 25% slower at 1920x1080.
Mass Effect 2
We enforced full-screen antialiasing using the method described in our special Mass Effect 2 review.
This game isn’t new and its system requirements are not high. The top-end graphics subsystems can produce over 300 fps, which is overkill. Still, we can note that the GeForce GTX 580 SLI is 50 to 80% faster than the Radeon HD 6990 here.
