What job should I choose on MPH Hub Workers page for 1080ti? Is NVIDIA - Cryptonight, Ethash, Equihash, Groestl, Lyra2RE2, lyra2z, Myriad-Groestl, NeoScrypt, Skein the best option? Why didn't they add "All algos" option?

Is there an algorithm I can use to stress-test my OC settings? Timetravel seems to be the most demanding, am I right? Or maybe I should leave my OC settings and remove troubling algos?
