Help with choosing a gaming laptop

[Casino]

I been thinking about getting a gaming laptop (no room to set up a desktop rig) but I don't know exactly how much power and what combinations to get. Most of my searches have narrowed it down to an MSI or ASUS set up.

My main question is, should i look for an i7 4700 series chip with a 900 series nvidia gpu with about 3gb

or

i7 4800 chip with an 800 series gpu with 3 - 6gb

also, most of my searches have been with 12 or 16 gb of ram but is that overkill? I dont do any video editing or that type of stuff. just want to use it for gaming and other everyday uses like internet and video streaming.

I am also open to any other suggestions beyond what I listed here. I want to keep it around $1500.

TIA
