Thank you so much for your help matey, received my omen yesterday And I have to say I'm really happy with it. It's quiet big though, thought it would be a bit smaller but the 120hz panel is amazing. Once again, cheers for your help buddy. Have a good one.

First, I'll avoid MSI GP series laptops as their build quality isn't that great. Below I'll sum up all the laptops (from top to bottom, best to worst) since there isn't a laptop from above that can fulfill all your requirements

Display:
HP Omen
Other laptops except MSI GP offers entry level IPS panel (low sRGB)

Keyboard (all of them are good enough):
Y520
Tracer II-MK
HP Omen
Defiance III, Novatech Elite N1777

Battery life:
HP Omen, Novatech
Defiance, Tracer, Y520

Other things are pretty much the same

In my point of view, I would avoid Tracer II-MK (small battery, short warranty) and Defiance III (SFF which isn't good for powerful hardwares in cooling, also small battery). At the end it comes down to your own choice where you have to decide which part you want to sacrifice (for example short battery life at lower price)

I guess you're the only one that is willing to give an input on my topic, I mean if you could suggest a really good laptop that could run Cs:Go type of games or league of legends, that is really thin and has a beautiful display with a decent battery life, i would be sold if the price is lower than that of the inspirion 7577. Thank you for taking the time to help me out.

I'll order both from amazon and use their return services. thank you.

Thank you, it just grinds my gears when my friends that want to play games refuse to invest into a desktop because they have laptops that "do the job". Playing league of legends with 45 fps and blocky frames just annoys me. Hopefully I'll make most of them reconsider.

Doing that right now, thank you.
 

Speed- will downclock if it is lower than the other
Cas- dosen't matter
Voltage- MOST IMPORTANT, make sure it is the same voltage or the ram will not work AT ALL

He's right
