Your system should be ok for a lower detail setting - 1GB ram would be better. However, the graphics card is dire. My mate has one of those and has to play the same games I have on my old and slower system in a lower resolution than me. Try the demo when it comes out before buying the game perhaps, but I'd recommend spending a little bit of money on a graphics card with a bit more power. You don't need to spend much to improve on that card to be honest. That said, usually TW games can be played on a low graphics detail setting, and CPU power et al is important, so your system should cope. Well I hope so, because your processor is a tad faster than mine!
