Whoa!! Those are soar temps. Play on a flat surface. Say goodbye to your bed. Get a laptop cooler.
My laptop's GPUs(GT 650m's) are clocked way above GT 755m's and they never go above 74.
Ideally you want them below 85 for long a long healthy GPU life. Keep CPU in the early 80s, preferably in the 70s for prolonging it's life.
It's on a flat surface alright, nothing more I can with that right now.
Just down clocked both CPU and GPU, now CPU is less than 80 and GPU less than 85. Performance does not seem to be changed much.
