Greetings, I would like to upgrade the video card on my computer. However, I'm not sure if I'm using PCI or PCI express. I downloaded one of those detection programs, but it doesn't really say PCI or PCI express. Though, it does say I have an Intel(R) Q965/Q963 Express Chipset Family. Does that mean it's a PCI Express because I'm not sure. I'm also now sure what kind of power supply I have. I'll open it up and see. I just wanted to be sure I knew what kind of video card to get.
