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 is the most demanding game in our suite and it too shows little difference between the factory-overclocked GTX 980s. Though, if it's every last drop of performance you're after, then the Gigabyte and Galax cards do lead the pack, and out of the two, the Gigabyte just about has the upper hand.
