Hi. GPUs, as with almost any decive, have specs that may or may not support your machine. Just make sure that the card you get will fit. They come in a couple of interface configurations such as AGP and PCIe. The PCIe is faster, all things being equal. That card (or chip) should be pretty fast on its own. If you have a PC with an open PCIe port (and it does not sound like it  laptop?) then get the fastest, most powerful card you can afford. You can always put it in a better machine if you upgrade.
