I just bought Sims 3 on ebay, and after downloading the game, I got a message that my video card does not support the game. I am trying to upgrade my card but have never done it before. What card does Sims 3 need? It says something about it needing to support at least Shader 2. I was able to determine that the card I have is Intell(R)82845G/GL/GE/PE/GV. Could someone please help me with what I need to do. Thank you.
