I presume this is a Laptop, Correct?
If it is a Laptop you need to go and open a ticket to your Laptop's Support site and find out if you can upgrade the Discrete GPU card and which GPU card is supported by your laptop.
Depending on your laptop model, you need to know how the discrete GPU card is connected inside your laptop or whether it is soldered to the motherboard.
If this is a Desktop, you need to post your complete computer information.
