Ultra Quality Performance
Moving from high to ultra has a huge impact on performance so we dropped several cards from testing as they couldn't handle this quality.
For an average of 60fps, you'll want the HD 7870 or GTX 680. We're not sure if we've ever seen those two cards sitting next to each other, so it seems like there's something that is really hurting Nvidia's cards (note that TressFX is off).
In another first, the HD 7970 GHz Edition tangoed with the GTX Titan, slipping behind a few frames in the average results but doing much better on the minimum fps.
The minimum frame rates of the Nvidia cards were quite low and we see this most notably with the GeForce GTX 670 which averaged 61fps but had a minimum of just 28fps.
This time the GTX Titan is just barely able to outclass the HD 7970 GHz Edition, while the HD 7950 Boost was the first card to break 60fps, though you could probably get by just as comfortably with the standard model.
You won't be playing on ultra quality at 2560x1600 without a respectable graphics configuration, as the GTX 680 was reduced to a mere 33fps while the HD 7970 fared better with 45fps.
