[HollowKira]

Hi, I'm planning to buy a laptop this afternoon and I'm thinking of asking you guys here in tomshardware for your opinions on these laptops. Sorry for another which-laptop-should-i-get thread. Thanks in advance. these are all the best I could find. Laptops are kinda limited here in our area.

asus x55LB-XX19811
intel i7 5500u
8gb ram
2gb nvidia gf 940m

asus X550LNV-XX24H
intel i7 4510
8gb ram
2 gb nvidia gf 840m

lenovo z50-70
i7 4510u
4gb ram
4gb nvidia gf 840m

acer aspire v15 touch v3-572pg93rl
i7 4510u
8gb ram
2gb nvidia 840m

acer aspire e5-571g-73st
i7 4510u
8gb ram
2gb nvidia gt840m *edit: i guess there's no nvidia GT840m. I think this is 840m
no os

*all are worth $1k (I'm from asia and that's the equivalent to USD)
*all are 1TB HDD
*all are 15.6"
*all except the last are windows 8.1
38.5k
*usage is for work (excel, photoshop, and I'm a gamer although I am very much contented with low/medium settings)

Perhaps the best one is X55Lb, it have the best specs based on the comparison
