1440x900 - Gaming Performance
Most cards we tested can handle DNF with its highest quality settings at 1440x900. The GeForce GT 430 ($60) for example averaged 55fps, while the Radeon HD 5670 managed 57fps. Both provided very playable performance, even though neither is considered a "gaming" graphics card.
The Radeon HD 6670 exceeded 60fps without breaking a sweat, as did the old GeForce 8800 GS and Radeon HD 4770. Again, despite using the highest quality settings possible, old graphics cards such as the GeForce 9800 GT cracked the 100fps barrier. The ~$170 GTX 550Ti achieved 145fps.
