Need some details on the computer. Manufacturer and model number so that we can see what's there and what would work. With any video upgrade, the power supply is always a large consideration, you need to take off the side cover and look at the label on that. Need the manufacturer, model, wattage, and very importantly the output in amps for the +12 volts. There'll be a little chart and where it says +12 look at the corresponding number, ie: 14A. Also get the +3.3 and +5 outputs while you are there. Is there a video card in there now, or is it onboard? If so, what is the make and model of that.
Often, with any video upgrade, a power supply upgrade is also required to run the card. Being an older machine, you wouldn't be able to put in one of today's "power sucking beasts" so it might be ok, but only because the game you want it for appears to have low system requirements. Will see with the detailed specs.
