The best recommendation I can give Civ IV is that on "Warlord" difficulty, it plays like Civ II with a better graphics engine. And Leonard Nimoy, of course.

I have an ATI card and had the "render" error that is now on the Civ IV website. I managed to fix it myself, doing essentially what they said - update drivers and reload direct X.

EDIT To reply to Strategia - I can't put my finger on it, but I didn't like the way culture was implemented in Civ III and I just couldn't seem to do well in the more advanced levels of game play. It was frustrating and I couldn't ever seem to get an edge on the AI. Civ IV isn't like that and I can't be more specific than that.
