Could you recommend a video card for me to use with?

Whats the best cheapest used video card I can get off ebay that can run games like galactic civ 2 without problems. My budget is below $40 but I'm only looking to spend aro8nd $25 since I know ebay is a place of deals. My computer is 3.2 ghz celeron emachines with 1k ram.|||A good card for under $40? Good luck.
