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 bolstered by higher clocks, the reference GTX 770 still falls some way behind a regular GTX 780. It should, as well, as the Tesla-derived card is almost 70 per cent more expensive.
We asked other members of the office team to distinguish between the in-game performance of the three cards; they couldn't - our per-second graph reinforces just how close these three GPUs are to one another.
