Each packs adds various new items, and adds to the game.

The minimum requirements for the base game are as follows

2.4 GHz P4 processor or equivalent
1.5 GB RAM
128 MB Video Card with support for Pixel Shader 2.0
Microsoft Windows Vista Service Pack 1
At least 6.1 GB of hard drive space with at least 1 GB of additional space for custom content and saved games
I've read that with each expansion pack that you install the longer load times will be (depending on your computer). I've looked at the specifications that are recommended, and my computer exceeds them however I'm skeptical. I'd rather not sink a lot of money on something that won't run well.

I figure that if I were to buy The Sims 3 plus all the expansion packs the minimum requirements would probably raise.
