CPUs can play a role as your PC's brain, but on gaming laptops, graphics cards play a role in the heart.
To get the right graphics card to meet your gaming needs, you have to consider a few things seriously.
Model Number
The ultimate performance indicator of a graphics card is its model number which represents the graphics processor (GPU), memory bandwidth, and clock-rate combinations. The format is - brand name + model number, such as Radeon RX 480 4G, or GeForce GTX 950.
Memory
Choosing a graphics card based on memory is one of the biggest and most common mistakes of gamers.
If you are running a very large resolution (three monitors on 4K display), then there is no need to really care about the amount of RAM you have. If you use a resolution of 1920 × 1080 or higher you will have a high quality model in your first consideration, with which there will be more memory by default.
What you really have to consider is bandwidth.
Compatibility
Before buying a graphics card, look at the amount of physical space you will be given for the card, otherwise you can catch it for selecting the wrong dimension.
There are a few things to consider about buying a graphics card, but the above mentioned topics are more important.
