Okay, you do not need 16gb's of ram. Anything over 8gb's is complete overkill, unless, you do video editing or heavy photoshop.
Getting a part right when it comes out is the worst idea imaginable for anyone who doesn't have money coming out of their ears.
Also, the laptop you linked is good. I suggest getting a cooling pad and making sure the laptop has good ventilation. Biggest problem with gaming laptops is they get VERY hot if they do not have good fans.

QFT really 16gb ram that's just crazy and waste of money. I would invest more on the graphics card side for best performance. Also try to look out for laptops with good vent holes too.

Probably my post is useless now since everyone already gave you such good advice but I tried -shrugs-.
