ASUS ROG G56JR external GPU?

[OmniTeus]

Last year I bought a gaming laptop - ASUS G56JR. So far, I've been pretty happy with it, but I'm somewhat disappointed in the GPU it came with. Now I'm thinking of getting an external GPU for it. Is it possible to do it for this model without having to carry a big box around? And if yes, how? I know it's more efficient to buy a desktop, but I don't have that option right now, as I travel a lot between two locations, and I like to play games in both of them.
I should also mention that I don't really have any experience with installing external GPUs, I just read about in the past couple of days.

Thank you.

I added the specifications of the laptop, hope there's nothing relevant missing.

Asus G56JR-CN141
Processor:Intel Quad Core i7-4700HQ, 2.4 GHz
Graphics Adapter: NVIDIA GeForce GTX 760M, 2 GB, DDR5
Display: 15.6 inch, 16:9, 1920x1080 pixels
8 GB RAM, DDR3

Hi,

Unfortunately if you're thinking of installing an eGPU on your laptop you may have to sacrifice your wireless capability.

Here's a sample of a eGPU: http/www.amazon.com/Laptop-External-PCI-E-Graphics-Card/dp/B00Q4VMLF6/ref=sr_1_3?ie=UTF8&qid=1457100591&sr=8-3&keywords=egpu

You'll also be required to use a power supply in order to power the graphics card you'll use for your laptop. I won't actually suggest using an eGPU specially if you'll be carrying your laptop around.
