We review the MSI Radeon R9-290X Gaming OC. The cards equipped with that Hawaii GPU now is proper cooled thanks to the TwinFrozr cooler and steadily running and purring at just over 70 Degrees C, that’s under full gaming load. The 2816 Stream processor based Hawaii chip will get paired with 4 GB GDDR5 memory running along a 512-bit memory interface. The card itself is fully customized including component selection, custom PCB, custom cooling, well .. custom everything ! Powered through 8-Pin + 6-Pin power configuration it obviously runs at factory overclocked specifications as well. The card will clock towards 1040 MHz bit is clocked at reference clocks on the GDDR5 memory.
