Don't bother, because laptops -- ironically, especially so-called gaming laptops -- are absolutely HORRIBLE for gaming. You want to play games, get a desktop or a game console. You try playing games on a laptop, you're sure to shorten its lifespan significantly. Which is actually why so-called gaming laptops are so awful. The amount of heat generated by all those high end components is too much and starts slowly baking the internal components until they fail in 6-18 months on average.
Laptops on a college campus isn't as great as an idea as it sounds at first blush anyway. They tend to get stolen, you run the risk of someone accidentally spilling something on your laptop, and they still rather suck for taking notes on during a lecture assuming you can manage to avoid the temptation to spend the entire class period screwing around on Facebook or something similar.
My advice, which actually draws from some psychological research on effective learning habits, is to put all your money into a nice desktop or maybe even just some game consoles. You do all your school work on campus. If you need to type something up, go to a lab and use one of those computers. Part of your tuition is going to pay for those anyway. Everything school related is done on campus, and then when you're at your dorm/frat/apartment you can focus on the non-school things like playing some games. This helps to create a clear division between the two in your mind, and will actually help you to focus more when you're on campus. You will condition yourself to take on the persona of a serious student when you're on campus, and off-campus you can be a regular guy. If you try and mix the two, you will find it increasingly difficult to resist the temptations of video games and other distractions in your dorm/frat/apartment if you're stuck doing some long boring project, of which there will be many. Each time you give into that temptation to do something else, it gets a little bit easier the next time. So it's generally better to just deny that particular battle and get all your school work done at school, and then do everything else at home.
