In theory, you can run any game you like, without a GPU. Of course, you'd have to disable graphics (completely). However, the game will still run. With an older GPU, such as yours, you can tune the game down, especially using the NVIDIA control panel.
Begin by turning every special filter and reflection/water effects and whatnot completely off. If everything runs fine, exit the game, and turn some settings on (just not water effects, ever). Over time, you will find a balance, where you achieve a reasonable frame rate and resolution. If you step things up too hard for the GPU, then set them back.
