GPU value in the DirectX 11 age
 

Today's value comparison spans 11 cards with price tags ranging from around $140 to $680. Since Nvidia has yet to launch a sub-$200 DirectX 11 product, we'll mainly be studying match-ups at $200 and upward. This exercise should help us answer questions on everyone's lips. Is the GeForce GTX 460 1GB truly a better deal than the 768MB model and the Radeon HD 5830? Should you get a Radeon HD 5850 or a GeForce GTX 470? Are top-of-the-line cards always ripoffs? And will Lindsay Lohan serve her full 90-day jail sentence?
