I have:
Asus p5ld2
1Gb 533 DDR2 Ram
Abit Rx700 Pro 256Mb
Dual Core P4 3.0 Ghz
All housed in an Antec P180 with 5 variable speed fans
I got the game on the release date in Australia.
Basically game very fast, no probs (I only play huge worlds, 3-7 civs BTW)
BUT....
Pre & post patch, consistantly get CTD after about 1500AD.
Usual sound/movie problems as well..
Not happy, as I am able to play every other game I have, NEVER with probs like I have with Civ 4.
Am extremely dissapointed, as I have been playing Civ since my Amiga 500!
