Help to choose gaming laptop. Big Four from PCSpecialists 1 of 4

Hello to everyone,
Like most of here I came with my own headache. Did my own big research and end up on these 4 models.
my budget is 2000 GBP Obviously less better :slight_smile:
I was thinking Asus Rog G752vy but he got 6700HQ cpu. and I found few laptops with better cpu so.
Anyway to get out of this confusion I need an advise from the side. So please help me if you can :slight_smile:

So the big four is:

  1. The 15.6" Octane II Xtreme
  2. 17.3" Octane II (customisable)

I never had an experience to purchase anything from PCSpecialist.co.uk so have no idea what kind of bodies they use to stuff all these parts in.
Maybe its better to buy branded laptop such as ASUS or MSI or Alienwareā€¦
Anyway, any ideas hints anything, will be appreciate.

Thanks in advance
