Bottom Line
The Z790 UD AC offers genuinely impressive specs and excellent value at $306.49—with a solid 16+1+1 phase VRM, DDR5 support, and extensive connectivity that makes it attractive for budget-conscious builders looking to pair it with Intel's 13th Gen processors. However, we have to be straight with you: multiple reviewers have encountered a critical Ethernet MAC address bug that Gigabyte refuses to acknowledge, and additional quality control issues including warped boards and coil whine suggest their standards have taken a hit. Unless you're confident you can work around potential Ethernet problems or don't rely on Wake-on-LAN functionality, you might want to carefully weigh these reliability risks against the savings.
