I need a graphics card for a certain reason, you guys told me it has to be pci one to be compatible with my dell inspiron 530. The first one is a DELL J9133 ATI Radeon X600 128MB PCIe Video Graphics Card DVI S-Video, and the second one is Dell Silicon Image Orion DVI PCI-E Video Graphics Card X8760. They are both fairly old graphics cards and I need to know if they will work before buying them online.
