Pretty similar to the one I suggested.This is my system. It is on the lower rung of good systems, so maybe it'll give you a jumping off point... By the way, Civ IV runs perfectly.
Intel P-4 HT 3.0GHz
2.0 GB Corsair DDR-RAM (4 x 512 MB)
256MB GeForce 7600GS
You can buy this system for 450-500 dollars.
