I'm planning to buy a company owned laptop from them. It's an HP Elitebook 8460W - CNU2121NVS. It currently has an AMD FireProT M3900 1 GB graphics card. What I want to know is it this laptop can be upgraded with a newer graphics card. Like a GTX970M or greater. I don't know much about graphics card, so if you know then that would be great. Here is a link on amazon.
