I do not plan to overclock my speeds to allow ram to run at ddr 12800. My MOBO doesnt allow 12800 without OCing and it runs at max 10666. Now my question is if I buy 12800 ram instead of 10666 (so if when I do upgrade I have better ram.) Will I see a difference in performance from underclocker 12800->10666 over just 10666 ddr ram.
