Galaxy Xtreme Tuner HD is a GPU monitoring and overclocking tool from Galaxy/KFA2. It works like EVGA Precision or MSI Afterburner but is missing some features such as GPU and memory usage monitoring. The program supports NVIDIA graphics cards (tested on an EVGA GTX 480) and does not support ATI Radeon cards.
