Can i switch the graphics card on the lenovo think pad t510?

I want to know first of all if there's one besides intel integrated hd graphics. And second if not is it possible to have one put in. I have an intel core i5 m510, and want something better than the hd graphics that come with it.

Can my PC run skyrim, Arma 3, or Insurgency?

I have a Lenovo Ideacentre K230. My graphics card is a NVIDIA GeForce 9300 GE TurboCache if anyone asks. I really want to get one of these games for PC, but I'm not sure if my PC can get atleast over 25 FPS on them or something like that. If you want more spec information on it, just search the PC up.
