First off, i am not sure language that is...thus i could nto use a translator program.
But i could still figure out some things
Your video card is very weak...as is you CPU and RAM. To put it bluntly, your not going to be able to run WoW with that setup.
I believe the RIVA card was an AGP card, so if your going to upgrade then you will need a card that is AGP 2x compatable
But i would really think about not upgrading, saving some more money, and getting a new rig.
