Searching for an ATX motherboard compatible with the 3900X.
I'm setting up another PC and would appreciate some advice on a suitable ATX board for a 3900x system. Since you're not planning to use SLI or PCI-E 4.0, an x570 isn't necessary—your main benefit seems to be quicker memory speeds rather than higher MHz. You mentioned tighter timings matter more than raw frequency, which aligns with your needs. It will mostly handle business tasks like video/photo work and CAD programs such as Solidworks, and you might even replace your 8700K gaming rig because keeping both would be hard. You'll also be gaming at around 165Hz. Right now, I'm considering the MSI X470 Gaming Pro Carbon.
It looks like you're considering different options for your build. The non-extreme X570 boards are priced around the same level as the more powerful models. For a solid choice without heavy overclocking, the MAX-series board offers better support and a larger ROM chip for full BIOS updates. If you prefer something slightly upgraded yet budget-friendly, the Gaming Pro Carbon is a good pick, especially if you're looking for a bit more style at $165. Alternatively, the Asus TUF series provides a nice balance of features and price at $165 as well.
I suggest the ASUS X570 TUF, as discussed earlier. For a $500 PC build, don’t skimp on the motherboard.
the power consumption indicates that non-X570 models are better suited for managing the 3900X, but there are few of them available and they tend to be expensive. even more outdated boards might still offer memory overclocking potential.
You're correct, the X570 isn't essential; focusing on the X570 series pricing offers better value when comparing older motherboard features and build quality. Still, consider getting an AM4 motherboard like the Taichi X470—it can smoothly support all modern CPUs and comes with solid connectivity options at a reasonable cost.
It really depends on the specific X570 model you're considering. You're right, it's not that surprising given the recommendation for an older generation motherboard. A $210 board isn't unreasonable, especially since most higher-end X570 boards are priced similarly. I suggested a B450 board at $115, which seems reasonable compared to the $210 option. Both the B450 and X570 boards you referenced are more affordable and offer comparable connectivity features. Your reasoning appears to be off.
