Ha ha ha... no, I don't even think you could pull 800 X 600 @ 30 FPS with that. There's no way I would consider dropping $40-$50 for that game with your system specs. Your best bet is to find a friend who has it on Steam and have him sign on to his Steam account on your computer and take it for a spin. This is totally legal and allowed by Steam.
long story short, spend some cash on a dedicated graphics card. there are a couple of gpu's out there that don't require an additional power plug from the power supply to them, that would play that game decent. need to know what your power supply is before recommending any larger graphics cards.
