BioShock Infinite
BioShock is fantastically playable and looks great on the PC. We benchmark a 45-second section near the start with all available eye-candy turned on.
Anyone who has followed the GTX 960 launch will know the story: performance is excellent at FHD, just about manageable at QHD and terrible at 4K UHD. In BioShock Infinite, you'd do well to notice any difference between Gigabyte's G1 Gaming and WindForce 2X models.
