Borderlands: The Secret Armory of General Knoxx
The GeForce GTX 590 is again ahead of the Radeon HD 6990 which is an uncomfortably low bottom speed.
Grand Theft Auto IV: Episodes From Liberty City
Besides noting that the dual-processor cards are similar in performance, we can also see that the multi-GPU technologies have low scalability in this game. I knew that from the previous test session, though.
Left 4 Dead 2: The Sacrifice
Considering that each graphics solution delivers a very high frame rate in Left 4 Dead 2, the comparison has no practical worth but AMD fans can be pleased that the Radeon HD 6990 is as many as 23 fps ahead of the GeForce GTX 590 in the hardest display mode.
Metro 2033: The Last Refuge
Today’s graphics cards are still not advanced enough to run Metro 2033: The Last Refuge at the highest graphics quality settings. This is indicated by the bottom frame rates which are the same for the single cards as well as multi-GPU configurations. The GeForce GTX 590 is ahead of its dual-processor opponent at 1920x1080 but the two are equals at 2560x1600.
