With regards to gaming laptops, I'll never buy one again. I have one that I purchased specifically to play E: D when I went away for a couple of months. I didn't play it once, and got to lug a huge heavy laptop around the world (instead of an ultrabook). And of course, it's out of date now and I can't do anything about it ((unlike my real gaming PC, where I upgrade components quite regularly).
Though of course, I do realise that the above is an entirely personal view. I'm sure gaming laptops are preferable for some.
