Crysis 3
Crysis 3 is a beautiful-looking game that continues to tax high-end systems. We've FRAPS'd a 30-second section near the start of the game, with lashing rain, numerous reflections and full DX11 pomp on show.
As an example of why out-of-the-box frequencies matter, Gainward's decent core clock and overclocked memory make it much faster than our poor-Boosting reference card, and we can really tell the difference when playing the game at 2,560x1,600.
