Hey ZRong,

I've got a few friends who are using the GE60 (even one college student who games overnight every weekend, Lols!)
and no issue of CPU or GPU throttling wohh. At what point did the bottleneck happen?

Btw, are you referring to this article by Notebookcheck? They reviewed the GE60 with Nvidia 860M GPU and some of the comments also stated that Furmark isn't a recommended stress tester as Nvidia throttles their cards when they detect that program running. Seems it's to protect the card from the 'extreme electrical currents' generated from the Furmark test.

Anyways, hope you can share your experience on this as there are sifus here to help.

Good luck and all the best with your gaming!
