i was also surprised hearing laptop video cards can be changed . never heard that before, it is only desktops that can really be modified/upgraded i.e changing processors, video cards, ram . the last time i checked with laptops the only upgrade you can do is ram upgrade. changing video cards & processors is as good as changing mother board, which is as good as changing laptop, since laptops come with integrated VGA & processors. I am open to opinions different from mine
Before anyone goes out to buy a laptop, decide what you want to use it for (mild work/hard work or play) and go for the one with recommended specs.

it depends the thing is that most laptops in Nigeria uses non dedicated v ram which are usually small and can't be changes but those that are using dedicated ones like nvidia can surely be changed

please how can i know the dedicated graphics before buying it
