Interesting looking project!
Gigabyte showed us its new range of auxiliary VRM boards for graphics cards, designed for professional overclockers. The board has to be manually soldered onto your graphics card, it supplements your card's GPU power domains. The card features a high-current power stage, which draws power from five 8-pin PCIe power connectors. The power stage is actively cooled by a fan-heatsink. While your GPU may never need that much power, it makes near darn sure that it doesn't suffer from voltage droop, which destabilizes your record-seeking OC. Such devices have been attempted by other VGA makers in the past, famously, the EPower Board by EVGA. The company also showed off its first liquid-nitrogen evaporators for GPUs.
