Customer Reviews:
I bought this board for my wife’s computer from another site. I don’t overclock*, and she doesn’t play much for games. It’ rock solid stable with Ryzen 3600, XPG SPECTRIX D60G 16GB (2 x 8GB) DDR4 3200 (AX4U320038G16A-DT60), WD_Black SN750 500GB NVMe M.2 drive, and Sapphire PULSE Radeon RX 580 8GB (100411P8GOCL) video card. | One thing that’s a gimmick on this board though is the M.2 wifi slot. Not only was it hard to find a wifi card that worked, but also had an antenna wire set with it. The cards I found on Amazon didn’t have the wires included. Any that I tried also wouldn’t snap in, so basically weren’t within the standard. I ended up finding another AX200 M.2 card with the antenna wire set included on another site, which is no longer available. Using the M.2 has no performance increase over using a PCI-E 1x card, and was WAY more of a pain to find, order, and install. | Now for my * mark on the overclocking…overclocking is a gimmick in itself as well. The reason I say that is because for the amount you need to spend extra on aftermarket cooling, a better motherboard, and better RAM, you might as well spend less on the next best CPU. The only time I’d say overclocking isn’t a gimmick is if you have the best CPU already and everything to go with it. In that case you’ve already wasted too much anyway, so might as well push the limits. I prefer to just use my components as long as possible at solid stability. Any time I needed an upgrade for a game, the video card was the only thing needed (also why you should spend a bit extra on a good power supply).
