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 30-second section near the start.
The 290 provides GTX 780-beating performance in BioShock Infinite.
And looking at the per-second results shows that it, like the R9 290X, has more consistent performance than the also-graphed GTX 780.
