EVGA OC Scanner X has now been updated to version 2.1.0 and includes better power monitoring support for Nvidia's 28nm GeForce GTX 680 graphics card. A few improvements have also been made to NV-Z, which is EVGA's proprietary GPU information module (see: TechPowerUp's GPU-Z for comparison) and now gives GeForce GTX 680 users more control over base clocks, boost clocks, current and target power.
