The EVGA X58 3X SLI Classified is one hell of a motherboard. It is the most refined, most feature packed, and most overclockable X58 motherboard we've seen to date. The X58 Classified has a true 3X SLI PCI Express x16 configuration, utilizing NVIDIA's NF200 PCI Express bridge chip, along with an additional PCI Express slot that they claim is for dedicated PhysX. Overclocking features abound here as well, including support for dual +12V connectors to pump more power to the CPU, on-the-fly vCore alterations through a hardware control panel, higher-grade capacitors, 10-phase digital PWM, and a monstrous custom designed (passive) cooling system. These features are certainly designed for an extremely small niche market of buyers, but those who need these features are willing to pay for them.  The EVGA X58 Classified motherboard is engineered for those who demand more than just the best!
