I use AMD xp2400+ (2.0 GHz) cpu, 512 MB RAM (266 MHz buss), ATI 9800 Pro (128 MB RAM) and Turtle Beach Santa Cruz sound. This system does not give satisfactory performance with RTW no matter what graphics settings I use. I get less than 10 fps with more than 3000 men on the battlefield. I've had the system checked by a knowledgable person, and everything is working properly.
