I'm playing a new HOF attempt and I have about 800 automated workers. Turns take about 5 mins for just those worker moves (anims are disabled). This is Celeron 1.1GHz. How fast machine do you need (is there fast enough yet?) to play Civ3/C3C at acceptable speed (eg. wait times under a minute)? I haven't tried Sid yet, but seems like there can be thousands of units so it should be even worse.
