Pretty much all laptops, desktops, mice, keyboards, speakers or anything with the word gaming included has flashy lights. According to the market this is what gamers want.
If you must have gaming capable power without the flash go for professional business laptops. These are equally expensive but are designed to be powerful, yet discrete in appearance.
Go for one with hybrid graphics otherwise the power hungry graphics card will drain the battery when just running Word.
A mobile 1080 will be slower than a desktop 1080; just the laws of physics.
