Our friends at TechPowerUp has review the ASUS Radeon HD 7770. Do check out what they have to say about this mid range card.
ASUS is using their well-proven DirectCU thermal solution on the new HD 7770 DirectCU. The card also comes with a large overclock out of the box, yet stays cool and runs at super low noise levels. ASUS has chosen to follow the AMD pricing, so no price increase for cooler and overclocking.
