I have boxed mainly on laptops and played wow on laptops before that. Anything that stresses out the GPU will tend to make it run close to 100degC so that's pretty normal. On different models I have opened them and lapped the GPU cooler and applied arctic silver, but at most this makes 3-5deg difference.

Get a laptop cooler pad type. Don't expect it to make a big difference but it will do 2 things.
1. keep your testicles (apologies if you are female) a safe distance away from your boiling hot laptop.
2. keep the airflow under your laptop good. A lot of laptop vents are actually under the unit and the little feet on the corners are designed to give enough clearance for air to flow to them.

Other than that, expect the unit to run hot but don't worry because laptop components are designed to tolerate it.

Cheers
