BioShock Infinite, like Tomb Raider and Hitman Absolution, sees both R9 280X offerings perform very similarly to each other. As for playability, we've got solid numbers at both 1920 x 1200 and 1680 x 1050. It's only at 2560 x 1600 that we see our setups fall short of the 60 FPS number we need.

Looking at Battlefield 4, we can see that performance at all resolutions is strong with playable numbers being seen. Comparing the two R9 280X offerings, though, you can see little difference between the setups with the overclock and RAM not doing much here.
