1920x1200 - UberSampling Disabled
You're undoubtedly familiar with this phenomenon: resolutions go up, framerates come down. Such is true when testing The Witcher 2 at 1920x1200, as fewer graphics cards average 30fps and only three exceed 60fps. If you're content with the former, you'll need at least the HD 6790, 5830, 6850 or the GTX 460 to play with Ultra Spec settings. The latter requires today's single-GPU flagship, the GTX 580, or better.
