Images of AMD's Cape Verde 7700-series continue to surface this week, the lastest being of this XFX Radeon HD7770 1GB with a version of their Double Dissipation cooler seen at Arab PC World. Featuring a cooler which claims to reduce temperatures by 7C and noise by 13dB vs the reference design, this edition will also support 1GB GDDR5 RAM, dual mini-Display Port, DVI and HDMI output options.
There's still no official release date for the 7700-series, though cards are currently available for pre-order from various retailers.
