If you are looking for just playing games like the Sims then go for a cheaper graphics card like Geforce 4 MX (The reason I keep mentioning Geforce 4 MX is because I used to have one and still do and they play most games on the market now - apart from the very recent games like DOOM 3 & Half-life2), but if you are looking at playing the top of the range games then go for a higher expensive card which will lead you upgrading more parts of your PC (Processer)
