This is cool as ice <| sep |> in cpu heavy games it can make a big impact , but you ' re free to disagree . the idea behind the build was to make it highly upgradeable while still having good performance from the get go . bclk ocing is just a side effect of buying the z 170 motherboard . it ' s free performance i guess i could say , so there ' s no reason not to do it . if you really just want to cut down on every dollar then go grab a cheap h 110 or b 150 , but right now z 170 motherboards are cheaper than ever , so i ' d say it ' s worth to it to pick one up now . the cheapest motherboard on pcpartpicker atm is $ 36 . 98 so you ' re paying 26 dollars to give yourself a much better upgrade path , and as a side effect you can oc your ram and CPU . I don ' t know where else that 26 dollars could go to improve performance and upgradability to such a degree . it ' s almost enough to get you to an rx 480 i suppose , which wouldn ' t be a bad idea , but would be 36 dollars and lose out on upgradeability .
