Will it game? FX 5200 APG???

Hey guys, my sister's laptop recently died and while she saves enough money for me to build her a decent rig, she'll be using a computer i've had sitting in my parents attic for quite some time now. The specs are as follows:

Windows XP 32-bit
512Mb DDR RAM (i forget the speed)
AMD athlon XP 900Mhz
Geforce FX 5200 AGP


Anyways, she want to know if she can run WOW and i honestly don't have an answer for her. I know we used it sometimes for LAN parties to play guildwars and dawn of war. What do you guys think?

Taken directly from a WoW - Burning Crusade box...
