You can upgrade your graphic card according to your system requirements. It is noted that each motherboard and pc system support different graphic card. For this purpose you should visit market and consult the pc shopkeepers. Second option is to search an upgraded graphic card for your computer through internet. For this purpose I suggest you to visit the site ComputersSpecs,com which gives different computers specs, prices and free download drivers as well..
