1680x1050 - High Quality
When playing with the high quality preset, Medal of Honor: Warfighter is playable using fairly dated hardware such as the GeForce GTX 460 1GB, which averaged 40fps at 1680x1050, and the Radeon HD 5830, which offered 37fps.
In fact, the only cards that didn't break the 30fps barrier were the HD 6750 and 6670. Even the GTX 550 Ti and HD 6770 managed 32fps, which obviously isn't near our ideal 60fps, but it's still playable if you're not too picky.
The HD 6870 and GTX 560 made it much closer to our preferred frame rate with 49fps, while the HD 6950 was the first card to achieve 60fps. It's smooth sailing from there, with current-gen products like the GTX 660 Ti hitting 86fps.
