Thanks for ur reply, i did passmark test on laptop and the gtx 1070 got nice score 10k+ on desktop ( 970) got 9k+. So i guess the problem isnt actually the gpu, which it stays at 80ºc stable... Probably the cpu is holding it back i guess, i use intel xtreme utility to undervolt the cpu and it doesnt show that he is thermal throtling...
I'm currently using "whisper mode" from GeForce Experience to hold fps at 45 on witcher 3 ( ultra settings ) and the temperatures arent that bad, i guess i'm just a little disapointed with price/performance i guess... without whisper mode cpu reach over 100ºc and ofc throtle 🙂
I also did some research and i see this is a common issue with this version, maybe Asus can make a bios version with lower voltages for cpu and gpu to keep performance/heat more... barely.
Thanks again o/
