techPowerUp posted a review on the ASUS EAH 5850 TOP DirectCU

ASUS has released what seems to be one of the best custom designed HD 5850s. The card which supports DirectX 11 and Eyefinity is extremely quiet, offers better price/performance than the AMD reference design, comes with an overclock out of the box and supports voltage control via SmartDoctor.
