Crysis 3
Crysis 3 is a beautiful-looking game that continues to tax high-end systems. We've benchmarked a 60-second section near the start of the game, with lashing rain, numerous reflections and full DX11 pomp on show. 4xMSAA is enabled at 1080p and disabled at 4K.
Crysis 3 shows that not all games are equal. The Asus Strix posts a 50 per cent improvement over a GeForce GTX 680, so if you have one of those in the system, a GTX 970 represents a worthwhile upgrade.
This 4K test is for giggles alone. Even with antialiasing disabled no card can manage close to 30 frames per second.
