From the official Wizardry 8 website, here are the system requirements:
Q: What are the system requirements for Wizardry 8?
A: System requirements are: Windows 95 OSR2, 98, or 2000; a 233 MHz processor or better; 64 MB of RAM, a 3D accelerator with 8 MB of texture memory, 4x CD drive; soundcard and mouse.
In short, a game that looks and feels absolutely gorgeous that still runs on older systems.
Cheers,
