Our take on the Gigabyte X299 Designare Ex LGA 2066 Intel ATX Motherboard

The Gigabyte X299 Designare EX is a premium ATX motherboard for Intel's Core X-series processors on the LGA 2066 socket. It stands out with three M.2 slots, dual Thunderbolt 3 ports, a DisplayPort input for Thunderbolt pass-through, and a robust 12-phase VRM with generous heatsinks. It suits content creators and workstation builders who need fast storage, external display chains and lots of PCIe lanes rather than gamers chasing the highest memory overclocks. Against rivals like the ASUS Prime X299-A and MSI X299 SLI Plus, it offers more connectivity but a busier board layout and a higher price tier.
