BioShock Infinite
Making a really good case for game of the year already, BioShock is fantastically playable and looks great on the PC. We benchmark a 40-second section near the start.
The reference GTX 780 card doesn't boost very well at all, thus even the Asus model manages to run almost 10 per cent faster. The same is true of the GTX Titan reference beastie, and the four aftermarket GTX 780s form a tasty Titan sandwich in BioShock Infinite. Performance is very good at both resolutions.
