Hello everyone.
I'm starting to think about adding an external graphics card to my laptop. But there's one thing, I'm not sure if I have an PCI-e or the other PCI port (can't rember it's name). I have lenovo g510, it would be awesome if anyone could help me out. I know that you can open your laptop up and see for myself if there are those ports, but I'm currently not at home.4

This may sound kinda dumb, but from what I've read a thing called wifi card is in my laptops PCI-e prot, if I would remove it will it work? Ofcourse with the sacrifise of using wifi on my laptop.
Sorry for my english, I'm from Latvia!

Don't say i didn't warn you, if you buy that thing and it doesn't work. Your i7 is strong enough, but hard to say whoever designed that piece of hardware may have introduced bottleneck on the hardware interface its using. If it is going through wifi card part, i doubt the port is strong enough to handle the entire memory bandwidth needed by some gpus like R9 280 with 384bit. If it goes through m.2 ssd slot it would make more sense.

Just that you should really look into the hardware itself before buying. Its a one time purchase with no recourse.

No. First of all if you buy a laptop you forego all options on upgrading. Second, laptops don't have PCI-e that graphics card uses. And where in the world did you even get the idea wifi cards uses pci-e ports?

Don't even bother buying that product. These type of external solutions isn't compatible with most laptops and likely you'll just waste money and finding out it won't work. Second you will need to modify your laptop in some way and form to access whatever port it uses. If you say it uses wifi ports then you will need to take your laptop apart and retrofit the cables to it. Laslty the huge factor in it is your bios. Laptop bios can be locked and won't allow any internal upgrades to it, aside from DRAM and Storage.

Second, there will be huge bottlenecks using PC grade gpus on laptop cpus. If you're laptop cpu isn't up to par, you will never use the full performance potential of the graphics card, hence wasting money again. With that external hardware, you will also need to buy an power supply for the graphics card which means putting more money in again.

You're much better off just finding and building a budget PC yourself as a gaming rig. There are many alternative cheap builds out there that offers fantastic performance over whatever laptop you have and you'll be happier.

If you've actually read through the product reviews customers posted, there are quite few people that found their laptop wasn't compatible.

Well thanks for the response!
The thing is that my laptop has 8gb ram, i7 quad 2,4 ghz. I think it's pretty good for a laptop. I have amd radeon 8750m.
In one video a guy showed off this external graphics dock, and he had a very weak 1,2 ghz procesor. If I remember correctly. So I thought it would run very good on my rig. Currently my budget is very low. 200 dollars, that's why I was looking at this rather than building my own pc.
