Solved! Laptop better than a desktop for cheaper?

[majdkhou]

So I've been getting this idea a lot lately, I'm not sure whether it works or not so I thought I should ask you guys.
A HP Pavilion 15-AU100NJ with i5-7200U 2.5GHz
Could I buy a PCIE Express (External GPU) and a GTX 1050 or a 970 or RX 480 and plug it in the laptop and play? I mean if this doesn't work with this laptop there must be a cheap laptop with a good CPU that it works with, I mean you get the concept.
But just wondering about something else.
I recently bought a Lenovo IdeaPad Y700 - i5 6300hq - GTX 960M 4GB and I'm not really happy with the performance, was just wondering if I could sell it and add a bit to my budget and get a GTX 970M or a 980M for a fairly good price? Thanks.
Also a side question, does it increase the response time or does it affect the input lag if this idea works? (a pro gamers sided question)

You're talking about an eGPU. Which requires a PSU to run it and the interface. Along wit hthe GPU.
No...it isn't cheaper or better than a desktop.

If it were that cheap and easy, we'd all be doing it.

A 400 watt PSU is 30$ and a GTX 1050 is 110$ and what do you mean by interface? The laptop also costs 350-450$ with no dGPU and a decent i5... That's 490-590$ which is decent enough to run a GTX 1050 and be half portable or so.

You cannot simply "add" a desktop GPU to a laptop.

1. You need to purchase a laptop with a Thunderbolt 3 port. Only expensive laptops have this port. The HP certainly do not have one.
2. You also need to purchase an external case for the GPU like the Razor Core External Graphics Dock which is generally designed to work with any laptop with a Thunderbolt 3 port, not just Razor's laptops. However, it costs something like $500.
3. While the Razor Core can work with other laptop name brands, you may have to wait for them to develop drivers for the laptop you want to buy.

Alienware sells the Alienware Graphics Amplifier for around $200, but it is only compatible with Alienware laptops.

If you are not satisfied with the GTX 960m, then I would not bother with the GTX 970m. Sure it is more powerful, but not enough before you become dissatisfied again. I recommend you look at laptops with at least a GTX 1060 which is basically equal to the GTX 980m.

The interface between the laptop and the GPU. Link, please, to the one you're thinking of.

Those power supplies have nothing to do with running a GPU.
