TUL Corporation, a leading manufacturer of AMD graphics cards, announces an upgrade to the HD4770 series, the custom cooled PCS HD4770. Manufactured with a cutting-edge 40nm process and using the latest GDDR5 memory, the PowerColor PCS HD4770 represents an industry milestone in the advancement of gaming performance. The PowerColor PCS HD4770 clocks in with a 750MHz core speed and 800MHz of memory speed. Added to the HD4770 is our Professional Cooling Solution (PCS) made by ARCTIC COOLING.
