I'm OC my i7-2600k cpu to 4.2 GHZ with the help of the program Inel Burn. When i run the Burn test my cpu's temp is at a decent spot. However, i intend to run nothing but gaming on this rig and i was wondering if i really need this program? When i play games such as Planetside 2 or Battlefield 3 my cpu is around 20 F less than what the intel burn test puts on my cpu. Because of this, should i OC more?
