Firing up the Bioshock Infinite benchmark we found that the Alienware X51 R2 was more than capable of handling the latest version of Bioshock. You can see from the settings that we aren’t holding back and the X51 R2 was able to average over 81 frames per second at 1920 x 1080 and just under 117 frames per second at 1280×1024!
Hitman Absolution is a bit more demanding than Bioshock Infinite above. At 1920 x 1080 with the settings cranked up we were able to average 30.3 frames per second, at 1280 x 1024 our average improved to 40.8 frames per second. Obviously a little higher would be nice, but the game play was still smooth, lowering the image quality a bit would certainly increase the frame rate if you needed a bit higher fps.
Sleeping Dogs was no issue for the Alienware X51 R2, at 1920 x 1080 the system was able to average 41.8 frames per second and 62.2 frames per second at 1280 x 1024.
The Alienware X51 R2 didn’t struggle with the latest iteration of Lara Croft in Tomb Raider. With the image quality set on Ultra, the system was able to average 78.7 frames per second at 1920 x 1080 and 107.3 frames per second at 1280 x 1024.
