When you start looking into Gigabyte’s more expensive motherboards, you’ll come across models like the X570 AORUS Master. Yes, it’s pricey, but it gets you a lot in terms of performance, and it looks pretty good, too.

The four DIMM slots can take up to 128GB of memory, at up to 4400MHz, which is pretty good. It also takes ECC memory, which is a nice addition. The VRM section is a direct 14 phase with an Infineon digital VRM solution for optimal power delivery. There are heatsinks on the VRM and the chipset itself, so the motherboard will remain cool even if you push it hard.

All three of the M.2 slots come with their thermal guards, and you have nice additions like Wi-Fi 6, as well as an excellent ESS Sabre 9218 DAC to take care of the audio. Expensive? Yes, but very much worth it when paired with a 5900X.
