Looking for new graphics card?

It looks like you have an onboard video card, make sure you have a pci express slot. After that is the time to buy a new graphics card. I would recommend a lower range card so you don't have to get a new power supply. It doesn't matter what kind of ddr your graphics card is I would get a 6570 or something close to that. After you install the new graphics card you want to hook up the vga or dvi up to it and then install the latest driver from amd's or nvidia's website depending on the graphics card you buy.
