I bought a MSI GE72 Apache Pro. Looks like the GT80. I have a 6700HQ processor. Excellent laptop with lots of cooling capacity and processor goes rarely above 6-7%, so lots of power. I was forced to buy a laptop but I regret to have waited so long as I was afraid of performance and cooling problems. Gaming laptops are build for hard working so they have the best cooling. I blew up 1 laptop in past from heating problems.
Just my opinion. No need to agree or disagree but ... When it comes to PC's I believe in overkill. Buying 2nd best now gets you 8th best a year later because technology marches on ... fast. When it comes to Laptops I believe in roadkill.
Like many said obtain some cooler for that and change video card to something which is really multi monitor, even some old 10 years old I would say premium cards do have multimonitor ability and costs peanuts now for everything you want from them.
