Honestly it probably won't happen. The only way you would be able to change the graphics card in a laptop is if you had some sort of very high end laptop with interchangeable GPUs. Most of the time, the graphics core is soldered onto the laptop itself, and you would need to be highly skilled to remove and replace it. Most human people are not able to.
You are pretty much stuck there. What are you doing with the laptop in terms of games or productivity or whatever?
