Need Advice

[garfienaz]

Hi Guys,

I just wanted to take some advice from expert users of KeyShot.
I brought a laptop 7 months ago with specs of ;
ASUS
Intel® Core™ i7 4720HQ Processor Windows 8.1
DDR3L 1600 MHz SDRAM, 2 x SO-DIMM socket for expansion up to 16 GB SDRAM
17.3" Auto Full HD (1920x1080)
NVIDIA® GeForce® GTX960M 2GB GDDR5
1TB HDD 5400 / SSD With 256 GB RPM
This laptop is called republic of gamers so I intended to get high performance from this laptop because of my lower budget compare to  any mobile workstation with the same specs .
I  use Sketchup for 3D model making and Keyshot 5 for rendering. (Mostly interior scenes with area, point lights)
I am satisfied with these specs unless there is no light and my scene has no ceiling. So If I try to add some light into my scene ,the render time and the real time rendering frame  is getting slower . That is because I would like to replace my laptop (I wouldn't use a desktop because I have to carry my laptop to work everyday, so I am a mobile user)  with the specs of:

Lenovo ThinkPad P70 20ES - 17.3"
Processor E3-1505M v5 (4C, 2.8 / 3.7GHz, 8MB, 2133MHz)
Memory 16GB ECC DDR4
Storage 256GB SSD PCIe NVMe Opal2
Display 17.3" FHD (1920x1080) IPS
NVIDIA Quadro M4000M, 4GB memory

-OR-

I really need  an advice  whether or not I should buy this Lenovo. Do you think it is worth to give this price (£2866)  or (MSI--£2699).

and the last option (looks best option as price and specs--- Alienware--£1898)

I am looking forward to hearing from you.
