What kind of FPS do you want? Tactical, teamplay or maybe fast action? I recomended to you play SWAT 4 with DLC - tactical, Battlefields - teamplay or Call of Duty 2, 4 and Modern Warfare 2. Don't buy Black Ops, I have it on my console but it's worse than Modern Warfare 2 IMO. If you have PC you should play: SWAT 4 DLC, Call of Duty 4 and Battlefield Bad Company 2 DLC.
