No, graphics cards in Laptop computers are not usually replaceable.
If that card is dedicated (when you open up the laptop and you can pull the graphic card out of his socket) then you can change it to a 680M or even 970m or a 980m
I'm rocking a Clevo P170EM with 7970M and had before a 680M. The only problem I have at the moment is Win10 don't want me to install the driver for that card because win10 and switchable graphics are a mess to begin with.
But first tell me what is your laptop.
Sell that laptop and buy a new one with the graphics you want. Ignore anyone who tells you it's a simple procedure. Laptops are not designed to allow these type changes.
