In reality you don't want to go for a gaming laptop, ever. Reason being that they are not future proof in the sense that you can't buy them a new graphics card, or what have you. Maybe if you're super tech savy you could, but you're clearly not. But also because, having owned both for many years, laptops tend to mess themself up and they are sensitive to heat. That may sound weird, but every laptop gets eventually to a "point of no return", what I mean with that is that should it get too hot and it shuts itself off, it most likely wont ever go back to being as good as it was. I don't know what it is with laptops, but once they are messed up it's hopeless to try fix them. Yeah they may be handy and, it's always fun to show them off to your friends, but investing in a gaming laptop is the worst kind of investment you can do. Learning how to build a gaming computer would be good for you, but you needn't build it yourself; if you have friends you can always ask for help, or if you find a trustworthy company to build it for you that's even better. Either way it will benefit you greatly to learn how to build a computer yourself, if not learn a few things or two as it's good to be able to fix it yourself if something happens. Anything madmade can go to shits obviously. Concerning FPS, yes the difference is absolutely there, if you plan on gaming the future generation of games a laptop you buy now will have trouble in the near future. When building a gaming computer you should focus on a decent motherboard, a decent graphics card and an SSD(once you use an SSD you will never want to go back to a normal harddrive) and RAM(you want to have 8gb of RAM at a minimum IMO). Get a good cooler (i.e Noctua) for your CPU should you want to overclock(altho honestly, this is NOT needed) and make sure you've a powersupply that can power your graphics card. Hope this helps, good luck.
