I ran tests during open beta against Benchmark. My findings are very different, however are typical of most games. The game is well optimized, however it doesn't take advantage of Hyper-threading. In fact you can increase your benchmark score by a few hundred points by disabling hyper-threading in the benchmark. Also this game doesn't get a much better score with more than 4 cores.

Some data I recorded using GTX Titan stock and i7 3930k. I disabled/enabled cores and overclocked in bios; rebooting for each test.
