Is it possible to change my lenovo(c440) all in 1 pc's graphic's card?

My pc spec's are
intel core i5
1gb nvidia geforce 615
1TB hard disc
4gb ram

Yes, it is possible. The 615 is a low profile card. So if you want to upgrade, get something that is low profile too, like a GTX 650/750. Also, get 4 more GB of ram. 4 is too little now.
