Which Laptop is best Dell, HP & Lenovo?

I would be using it for 3DS MAX and Gaming (like Assassin Creed 3, Prototype 2).

I'm more inclined towards Lenovo & HP R032TX because of price & Windows 8.1 is Installed. I want to know which would be best Dell, Lenovo or HP wrt durability, after sales in India, overall built.

Will there be notable difference in 1.9GHZ & 1.7GHZ. Also please compare 2GB ATI JET LE R5 M230 Graphic Card with 2GB NVIDIA GeForce GT 820M Graphic Card.

Mainstream Windows laptop mfg ratings:
Lenovo is the number one, followed by Asus, HP, Dell, and Samsung.
At the bottom of the pile are, from the bottom up, Sony, Acer/Gateway, and Toshiba.

Purchasing a laptop is a highly personal decision. You need to decide what type of keyboard you want: do you want a full sized keyboard or are you okay with something smaller? Do you like or despise the chicklet keyboards like apple uses? Do you want a backlit keyboard? Do you want a numeric keypad? Do you want a touchpad and/or point stick? Do you want 2 mouse buttons or 3? Do you want them above or below the touchpad? How large a screen: 13"? 14"? 15.6"? 17"? If you are highly mobile, then smaller is lighter. If you don't move around much then bigger means heavier but a much more visible screen. These are all things to ponder which have a significant impact on how happy you are with your laptop experience.

My Lenovo G555 died 3 times from video chip desoldering. I gave up.
My neighbors' HP equipment is regularly repaired or junked.
My 16 year old Dell Latitude still works, my Dell Inspiron is 10 months new, still fine.

All are the best and useful but i will go with 3rd option.
