MSI released its R4890 Cyclone OC series graphics card with 800 stream processors and 1GB GDDR5 256bit memory. MSI R4890 Cyclone OC series is the only HD 4890 graphics card in the market that has a 10 cm extra large PWM fan. Because of the low rotation rate of the big fan and the 8 mm SuperPipe, this card is quiet and stays cool. MSI R4890 Cyclone OC series is equipped with Military Class components, such as Hi-c CAP, SSC (Solid State Choke) and solid capacitors, to stabilize the GPU?s power supply and extend the life span. Because of the great improvement in cooling and high quality components, MSI R4890 Cyclone OC can reach a core speed of more than 1GHz while overclocking. Besides the MSI R4890 Cyclone OC MSI also offers a 1GHz factory clocked card called R4890 Cyclone SOC.
