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.
Crysis 3, on the other hand, requires more horsepower for fluid gameplay at the standard 1,920x1,080 resolution. That said, there really isn't a lot between a GeForce GTX 680 and the next eight cards in this lineup.
