In that case, Limey, here are the suggested system requirements:
Recommended:
* 3 Ghz Intel Pentium 4 or equivalent processor
* 1 GB System RAM
* ATI X800 series, Nvidia GeForce 6800 series, or higher video card
in addition to the minium system requirements, of course.
Basically, good luck, but it'll probably cost you a lot unless you already have a really good computer. Just ask yourself: is one game really worth it?
