Welcome aboard Herr Kaleun bistekka,
The system sounds fine but more RAM always a good thing no matter the game or program...
Sound card? I found running a PCI sound card can free up resources/cycles for more enjoyable gaming. I have an Audigy 2Zs that made improvement for me.
And updated drivers for all hardware seem to help a lot of people also.
Do not be afraid to play the game start with lower settings at first then gradual increases - but you should do fine with this system....
