Designed to show off the best Asus has to offer, the ROG Z690 Extreme and Extreme Glacial sport an impressive array of hardware and a long list of features, including PCIe 5.0 x4 socket (with five total M.2s), premium flagship audio, Thunderbolt 4, and robust power delivery. But priced at $1,099 and $1,999, you’ll need very deep pockets to fulfill your motherboard dreams.
