My old graphics card was only slightly better than yours (x600) and when I played the demo it looked great but was very choppy and slow. Fourtunately for me and you, this is only an issue in the demo. When I bought the game it ran 10 times smoother and I was able to play with low/medium graphics with very little lag.

But now I have an nVidia 7600 and can run the game with almost all highest settings and I'm enjoying it more than ever!


So I would recommend getting the game, I promise the real thing will run a lot smoother than the demo.
