NZXT Phantom 820


We're particularly interested to compare the performance of AMD's Catalyst 12.9 driver package to the more recently-released 12.11 beta driver, which the company claims should be much faster in a number of games.

Unlike many of the graphics card reviews you read, we're conducting our testing today in a closed chassis. After all, it can't be that easy to dissipate more than 500 W worth of heat, and we want to know what effect that has on real-world thermals and acoustics.
