I'm sorry to ask you this stupid question, but is it better to have more gpu usage or more mhz? My GTX 1060 can run on Adaptive settings at about 75% with 911Mhz, and on Prefer maximum performance at 45% with 1911 Mhz. Which one is better?
I am running cpu intensive games like gta 5 that are taking up 60-80% of my cpu. My temps are almost never exceeding 70℃ on my gpu and 60℃ on my cpu.
If my specs may help you:
Msi gtx 1060 6GT OC
I5 6402p
8gb ram
H110M CS.
