Dude, most laptops don’t have a discrete graphics card, but rather a graphics chip (IGP) which is mounted on the MB. These laptops are mostly designed for simple tasks and office use though.
If you want to play games and edit photos/videos, then a real graphics card is a must for you.
And yeah Maham, make sure that the RAM is upgradeable. But that would pretty much mean that you’d have to pay more $$$. 4GB are good for now though.
