That is not a "graphics card", that is the onboard graphics chip. To run these games you will need to install a discreet, or separate, graphics card.
HP doesn't list what wattage your PSU is, but it is most likely a 250 or 300 watt. Depending on the card you choose/buy, you may have to upgrade your power supply to run it. If you look through the specifications for graphics cards on Newegg, you will see that many list the minimum wattage recommended for the card.
So, basically, your main limitations are your budget and your willingness to crack the case.
