I've thought about doing this myself before because i don't use my gaming rig as much as i should, especially considering the amount of money ive put into it. But, i think you should keep it, and the reason why is because you'll more then likely end up kicking yourself for it later, what if you see some game you cant run on your laptop and you want to play it? It is smart to be thinking about doing things like getting your car but if you sell it then your like oh i want a powerful system again, it will cost you more to rebuild it then to keep it and just work and put money back for your car. Hope this helps you, or at least provides insight
