Okay, I could be wrong.

Either way I don't know if your system can handle it. My computer specs are:
Windows 2000
1024MB DDR RAM
Pentium 4 Processor 2.0Ghz
NVidia 32Meg graphics card (this is definitely the bottleneck)
lotsa hard drive space
1.5M Broadband

And it gets a little choppy when I have all of the graphics settings cranked up.

Hope this helps.
