System requirements for the sims:
FOR WINDOWS VISTA
* Windows Vista (Service Pack 1)
* 2.4 GHz P4 processor or equivalent
* 1.5 GB RAM
* At least 6.5 GB of hard drive space with at least 1 GB additional space for custom content
* 128 MB Video Card with support for Pixel Shader 2.0
So yes, more than enough.
The other option is to build yourself. 
Tease.
