hey guys. It's day two of insalling this card. I am noticing that in a lot of my games, particularly The Sims 2 and C&C: Generals ZH, I et strange graphical errors. In the Sims 2, the characters show as the person with a block around it, shadows around certain objects turn black, etc. In ZH, one half of the map works fine, but the other half has multicolor lines running through it. DOes this have somthing to do with eh card being underpowered? The specs are in System #1 of my profile.
