Ah ok, yeah that's the standard built in video chipset, the one that's built right into the motherboard. That 128MB isn't even really memory for the video card, it's your system memory that's being allocated to the video card
Those video cards are bare minimum type cards, they really aren't intended for gaming.. you might be able to get it running at the full resolution by turning all the options down in the game but then it'll look bad.
And WoW is probably the least intensive game for video cards out there right now.. If you want to play Starcraft II or Diablo III, you'll need to upgrade your video card.
