depends, if your wallet is mode 15600 [$ethereum$p] use your GPU (mining rig) if your wallet is mode 15700 [$ethereum$s] use your CPU (gaming machine) still use your mining rig
(well, actually it might still be worth trying mode 15700 with your mining rig GPUs, my 2600k does 13 H/s while my single 1060 does 21 H/s)
