Almost all laptop graphics cards are built in, so you can't adopt a new one. Although you can change the whole board if you are that desperate.

Depends on what type of pc u have if u have high end gaming laptops like alienware or msi ,chances are ur pc have a separate graphics card that is separeble .but in most laptops the gpu is soldered to the motherboard so unless its an expensive large laptop it prolly dont have an upgradable gpu .and swapping the mother board only works if ur upgrading to the same model with better gpu otherwise the case wont feat .so its better to get a new laptop with better power .but if u dont want that u can also set up a little box with a desktop gpu and a power supply then connect it to ur laptop through a thunderbolt port if u have one or u can use the mini PCIe slot which will of course bottleneck the gpu but will sill deliver good performance

Man if it's dedicated it could be changed I don't know a place but at least I know it could be changed

You can inport from foreign countries Ask this channel admin for instance @ethioshopch

Well, i think it depends if you have a desktop...u have a higher chance of it accepting a nividea or amd(which are cool for gaming). Anyways merkato teyk, u know the typical houses, yirga haile or mimi computers...weym demo bole akebabi ayitefam
