pretty easy. just make sure you have an empty pci or agp port for it. pci ports are the white ones. agp is the single brown one. if you are thinking of getting one, you probably dont already have one. so yea get an agp they are faster. apart from that.. all you need to do is open case, stick in card, screw in, close case.
