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.
Though we continue to be impressed with the GTX 780 Ti's performance, do bear in mind that the substantially cheaper GTX 780 is no slouch; Inno3D's HerculeZ, for example, is only a few per cent slower than the Palit in Crysis 3.
