New Gaming Laptop Or Custom EGPU in old Laptop

[Ataxion]

So right now I have 2 laptops one has a core i5-8250u which I use for school, web browsing, and very light gaming. My other laptop has a core i3-6100u and this is the laptop I would tdo the custom eGPU on. So should I make a custom eGPU for the second laptop or buy a new gaming laptop during black friday. the egpu would cost around $160 without black friday sales while the new gaming laptop would cost around $800 without black friday deals and I think will cost $500 during black friday.

I doubt either or those laptops have thunderbolt 3 for an eGPU, so you'll likely need a new machine.

I said custom egpu which basically means taking out the wifi card and connecting the gpu to the wifi card slot

From an experience from a few acquaintances, egpu tends to be either 

 

A. Super unstable

B. Is atleast 20-40% weaker than when used in another pc.

C. Compatibility is super dodgy

D. Will make you cost near the price of a new laptop.(gpu+dock is pretty expensive)

 

On the off chance it works, its jot that great. Especially if its running off express card or the x4 or x1 pcie.

That's... almost definitely not going to work well, if at all. That M2 slot for your network card probably only has 1 lane, maybe 2 if you're lucky. Performance would be awful and your laptop's motherboard very well could just reject it entirely because the hardware ID isn't whitelisted for use in the network slot.

is there a way to check if the motherboard will reject the egpu without buying it first
