128MB 3d Hardware Accelerated card required-100% DirectX 9.0c compatible and latest drivers (NVIDIA GeForce 6600+ / ATI Radeon 9800 Pro+)
That's from the specs. It would not cost much to get it running it just need a video card and you will be good to go as long as you have the ram to do it. but ram is cheap now days and ram don't cost all that much any more. if your only looking to play this game you can go with a GT nvidia card for the 600 series (gt 630 or GT 640) if your wanted a little play room then i'd go with a GTX 650ti or GTX 660. depends on your budget. if your really low budget then AMD has some very good lower end cheaper cards. Sorry can't give you names, not a AMD guy myself.
