Can I take my laptop to the shop and replace the graphics card with a better one as this intel graphics card only produces 68mb of whatever it is that runs games, software etc...

On low graphics options when running a game it lags and looks terrible. My computer specs are:

Intel core i5-2450M
Intel HD Graphics 3000
4gb ram
500gb HDD

What are my options?
