yes the 5200 is easily good enough to run the game, you might have to have the setting relatively low but im sure you will understand if you dont want to pay a lot. im sure you do have an agp slot unless your pc is really old. but if you are in doubt run sisoft sandra
www.sisoft.com which will tell you if you have one though im sure you do.
the 5200 will be fine and is a directx 9 card.
