Will my pc be able to run the sims 3?

Yep im pretty sure itll work on both! about the laptop, youll be able to use the sims 3 on it forsure, but it might take up too much space or slow it down tho. As for your desktop i really dont think you need to upgrade your video card, your computer will be fine, i know someone with the same model and the sims 2 works well on it, and the sims 3 wont be any different . Goodluck and Enjoy! (and i know, i cant wait til the sims 3 comes out! LOL)
