What do you think about these?

So, Im getting ready to replace my Lenovo G570 Sandybridge workhorse/Linux machine.

I have been looking in the 500-850 USD range but need some opinions. I have found some cool laptops on Newegg and one really seemed like a killer deal until I saw the review where they said installing another OS like Linux was essentially impossible. I really need it to support installing other OSes and that the hardware would work with Linux with as little hiccup as possible. Im going to list of the machines I have seen and am open to suggestions. At this point, I am brand agnostic.

I will separate by Brand:

##ASUS
ASUS Laptop R510DP-WH11

ASUS G501VW-BSI7N25

ASUS K501UX-WH74

ASUS FZ50VW-NS51 ← This one is the one that looked good until I saw it doesnt support another OS

##Gigabyte

GIGABYTE P15FV5-NE1 ← lacking Wireless AC it seems

##MSI

MSI GL62 6QF-628

##Dell

DELL Inspiron i7559-12623BLK

DELL Laptop Inspiron 15 i5559-7081SLV

DELL Inspiron 7559

##HP

hp pavilion 17.3

##Lenovo
Lenovo ThinkPad E560 20EV002JUS

Installing GNU/Linux should never really be a major issue

Also you should probably save up and just get the i7 version of the MSI laptop for $900

But you already have a desktop then?

yeah. I have my rig I built. I7-4770k, 16GB DDR3 1600Mhz, 2x SSDs, 2x HDDs. 7970Ghz Sapphire card. Gigabyte Z77 Matx board. It fits my hardcore gaming needs. I usually dual boot my laptop. I dont plan on playing games like BF4 and such on my laptop but would like to play more adventure/puzzle/RTS type games. I like Amnesia type games. I also wouldnt mind having the laptop be thin and lite one. No need for the DVDRW. I can always get an external if I need to.

i would also like to know what the "free gifts with purchase" are.
