The Corsair Vengeance 8GB 1600MHz CL9 DDR3 memory kit is a great performer in every regard. Being able to overclock this memory kit easily to 1866MHz is huge! While it does not win outright in benchmarks it is narrowly behind. The results are so close that it would be tough to actually see the difference in everyday scenarios. Its true value lies in its cost per GB where at just $5 more provides double the capacity of the highest performing 2133MHz kit!
