Custom Radeon R9 290X graphics cards start to hit the web and stores and today we are going to have a look at the ASUS one, the Radeon R9 290X DirectCU II OC. The Radeon R9 290X version is no different from other high-end DirectCU II cards from the manufacturer, you don't change a formula that works. The R9 290X DirectCU II OC features a custom PCB with a beefed up power design and is chilled by the latest version of the DirectCU 2 cooler. Other than the obvious the card has a factory overclocking on both the core and memory as well as a BIOS DIP switch allowing users to choose between a silent or a performance operation.
