what really matters is your GPUs power for mining, unless your CPU or motherboard are bottleneck your GPUs, to know if your getting the full hashes of your GPUs compare your mining hash rates to the ones on this website http://www.zpool.ca/bench . look for your GPU in the list and see others hashrates to compare.

if you are getting low hashrates then its time to upgrade your systems like rams cpu or motherboard.

last note regarding the GTX 1060, im using EVGA 6gb one and its a BEAST for the price.

happy mining :)
