Performance in Third-Person 3D Shooters
Just Cause 2
The Radeon HD 5970 and the GeForce GTX 570 SLI are fighting for top place at 2560x1600 and the latter wins, even though the gap is not as large as we might expect from their technical specifications. Nvidia's solution is 15% ahead in terms of average frame rate, which is hardly what we want from a $650 solution. The Radeon HD 5970 is even less appealing, though.
Lost Planet 2
Lost Planet 2 has rather high system requirements but even the GeForce GTX 580 meets them even at 2560x1600. The average frame rate of the GeForce GTX 570 tandem is higher by 47-48%. A dual-chip card like that would make a worthy rival to the Radeon HD 6990.
