Intel Core i7-875K (Socket 1156) Unlocked CPU
QUOTE: "The Intel Core architecture is one that has not always been a performance leader. The original Core Solo CPUs were decent, but not that great. Starting with the Conroe based Core 2, things changed. We saw Intel push the limits on performance at both stock speed and also for overclockers. With the launch of the Nehalem and Lynnfield CPUs we saw Intel greatly improve stock performance, but overclocking, while still pretty good, was not the same as it had been, especially for the top of the line CPUs.
To help offset this Intel has released a new “K” line of CPUs that are multiplier unlocked. This means that you have control over the multipliers for the CPU ratio and memory ratio, giving more options for a better overclocking experience."
