Well it depends, most cards that are even a couple of years old will still be able to run most new games, maybe not on max settings, but you'd still run it.
If you're looking to run all current games AND upcoming games on Max Settings, you would probably want to get a GTX 680 or a GTX 690, expensive, but both will last you for a long time.
You will probably need a dedicated graphics card to play any newer games.
The Radeon graphics cards are some of the best available. The card will improve the apperance of your games.
A good graphics card for low details on games is the nvidia 8800. I reccammend you don't get this just to be safe. To get normal to high graphics get the nvidia 9400. For high to best Graphics, get the nvidia 9800. For best Graphics, get the 260, 280, 285, 275, 290, (all nvidia).
The GeForce GTX 580 is either the best or the 2nd best graphics card

The best card from your preferred manufacturer. ATI and nVidia are the most popular makers.
