The risk to bear in mind with gaming laptops is their hardware ages and becomes outdated quicker, it's harder to upgrade parts and upgrades can be limited. Gaming laptops don't always last, depending on what you get because they can generate a lot of heat, which can affect the life of parts. So I usually err caution when it comes to gaming laptops. Plus laptops spec for spec are more expensive.

Nowadays I have a desktop computer, the nicest thing is they're easy to upgrade when something does break or you need new specs. Recently my HDD was on its way out and suffering heavily, it didn't take much to fit a new one and clone my old one onto it.

But really, it depends on what works for you, if you're not much of a PC gamer, the PS4 might be more economical over a gaming laptop or PC and can take some of the hassle away you might get with a PC.
