Yes, and it's easy on the system, too!
I can do my other work w/o slowing down the client noticeably. Plus, the heat is held to a minimum. A little warm to the touch, but that's all.
But I still use the cooling pad underneath it, the GPU temps are around 4 to 6C less. I monitor this with GPU-Z.
I've had this notebook only 3 weeks, and already have racked up 60,000 points within that time. Until I tried it, I never knew the power of GPU folding. It's awesome!
