Due to some recent sales I may be upgrading my i7-4970k to an i7-6700k, but want some advice on how this may affect my rig. Will I need to reformat(in which case I will not upgrade) or will this be okay as is and what are somethings I should do or look for before doing the upgrade itself. I've asked a similar question with regards to upgrading the CPU and Mobo, but don't need to upgrade both just the CPU.
