Help please?

[Shawna]

Hey everyone.  I hope it's okay to ask this.  I was wondering if someone could help me out.  I'm really not good with all the technical stuff, and I've been looking for a new computer to buy so I can play the sims 3.  Here are the specs, and if you can, please tell me if these will work:

•  Intel Pentium 4 3.0GHz Processor
• 2048MB Memory
• 250GB Hard Drive
•  Capacity 250GB

I'll be buying a new graphics card separately, so if you can just tell me if those will work or what needs to be upgraded.  Thanks so much.
