Would a rose by any other name smell as sweet? Sure, as long as the frame rates stay the same. Although the GeForce GTS 250 is a re-badged GeForce 9800 GTX+, the falling prices have kept this older, but still powerful graphics technology, very much in the game.

The Radeon HD 4850 hangs in there, competing with the GeForce 9800 GTX+/GeForce GTS 250 twins at the same price point. Each card will claim some victories depending on how well it works with a particular graphics engine, but neither will disappoint.

If you want to save a few dollars, the 512 MB version of the Radeon HD 4850 can be found for as low as $120.
