MSI proudly unveils its latest graphic card, the MSI NX8600GT Twin Turbo. This graphic card is equipped with two separate vBIOS on-board, which each carry dedicated GPU, shader and memory clock settings. By pressing on the hardware button on the bracket, a new (higher) clock setting can be applied without re-flashing the vBIOS chip. Users have the choice to use the Turbo function or the energy saving function. Overclock enthusiasts who want to tweak the vBIOS to find out the ultimate performance will have another vBIOS provided with this solution. For extra performance in overclocking status, MSI offers the shader OC model with a standerd higher shader clock.
