Best portable gaming laptop?

Hey guys, I plan to go to University soon and with me I'm bringing a new computer. However I am having trouble deciding whether to have the power of a desktop or the portability of a laptop. I know that I'll need to carry around my computer throughout my courses, however I don't think that gaming would be very immersive on a laptop. That said, are there any laptops that could give me an exciting gaming experience while still being portable? If not, what could be an alternative if I were to purchase a desktop? Any help would be much appreciated!

And please don't comment on my education priorities. I know how to control myself when it comes to gaming.
