External graphics card for laptop

[saksham_gupta]

I have an Asus N550JA-SB71T which comes with the following configuration:

15.6" FHD Touchscreen LED 1920 x 1080 Display
1TB 5400RPM SATA Hard Drive
2.6 kg (with 4 cell battery) (with Polymer Battery)
383 x 255 x 27.7 mm (WxDxH) (w/ 4cell battery)
4-cell Polymer Battery Pack
4th Generation Intel Core i7-4700HQ Haswell Quad-Core 3.4GHz Processor
720p HD Webcam and integrated Mic
802.11BGN
8GB DDR3 System Memory
Bang & Olufsen ICEpower, Sonic Master Audio
DL DVDRW/CD-RW Optical Drive
Illuminated Chiclet Style Keyboard
Integrated 10/100/1000 Mbps Fast Ethernet
Intel UMA HD4000 Graphics
Ports: 1 x USB 3.0, 1 x Combo Audio Jack, 1 x LAN, 1 x HDMI, 1 x SD Card Reader
Windows 8 (64 bit) Operating System

It's a pretty good configuration but I need a graphics card so I can play heavy games on it.

Recently I came across a few videos on youtube in which the connected a PCI-E slot through the WiFi connector port in the laptop and used it to connect an external graphics card. Should I consider such upgrade as I want to play games on my PC

since you have no thunderbolt connectors, that's the only viable option.
please note, that using this PCIe x1 interface will be limiting GPU performance.
I'd not recommend connecting high end GPUs in this way.
