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 exacts the largest performance toll of our games. You'd need the next class of card up, doubling the budget, for smooth gameplay at 1080p. The GTX 660 OC holds small bragging rights here.
The minimum fps, at around 25, makes the game feel sticky. We'd likely reduce the quality settings a touch.
