Gigabyte B550 Aorus Elite: Best budget motherboard for Ryzen 7 3800XT
The Gigabyte B550 Aorus Elite isn’t the cheapest B550 board at the moment. The thing is, cheaper models could have issues with running the 3800XT due to their less-than-ideal VRMs. This is the reason for choosing this model as the best budget motherboard for the Ryzen 7 3800XT.
If you want to get a board that will have no issues running the 3800XT, even overclocked, get this one. Its VRM section is good enough for you to push the 3800XT to its absolute limits. When it comes to other features, the Gigabyte B550 Aorus Elite supports fast, 4733 MT/s, DDR4 memory.
Connectivity options include a 2.5Gb LAN port. The board also has a pretty solid audio section, powered by the Realtek ALC1200 audio codec. It houses six USB 3.2 ports on the rear panel, which is excellent for such an affordable motherboard.
When it comes to SATA ports, the B550 Aorus Elite has only four of those. You’ve also got two M.2 slots (one PCIe 4.0 and the other being PCIe 3.0). Expansion slots include three PCIe x16 ports in total, but only one is a full-fledged PCIe 4.0 port that words at x16 speed. The other two are PCIe 3.0 slots working at x2 and x1 speeds. Also, the board includes one PCIe x1 port.
Gigabyte B550 Aorus Pro: Best mid-range motherboard for Ryzen 7 3800XT
If you’re looking for an X570 or B550 board to pair with the 3800XT, the mid-range market offers by far the biggest selection of quality choices.
