I don't want to spend over $100. The graphics on the sims 3 game and expansions are not as good as it used to be. I have over 4 expansions now, and the game has had multiple updates so its time to update the graphics card. I need something that can handle All of my sims3 games and the sims 4 when it comes out. I can go as high as $150
