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.
This is the best out-the-box performance we've seen from a GTX 770, though there isn't a great amount of difference between the various partner cards. The real gap is between stock and overclocked, with KFA2's LTD OC pulling out a near-10 per cent performance lead over Nvidia's reference board.
