I'm putting together a new PC for gaming, everyday household tasks, and coding. The parts I already have are a Ryzen 7 9850X3D, an ROG Astral RTX 5080, Corsair Vengeance DDR5-6000 CL30 EXPO memory, and two WD Black SN850X drives—one 4TB and one 2TB. I spent a lot of time comparing motherboards. I originally wanted the ROG Strix B850-E, but it's sold out in the US, so I bought the ROG Strix X870-E-H for about $300. Is this a sensible choice for the rest of the build? I probably won't use more than half of the available USB ports, so I'm wondering whether I paid for features I don't need or whether the board is still a good match. I'd especially appreciate feedback from anyone running a similar high-end system. Also, are there any limitations with installing both of my M.2 drives?

Unless you have a specific need for USB4 or the board’s additional connectivity, X870 doesn’t provide a noticeable performance advantage over a good B850 board. Your CPU and graphics card will perform the same on a less expensive motherboard, so it isn’t the best value-focused purchase. That said, since you got the board for $300 and can afford it, there’s nothing inherently wrong with keeping it.
For a gaming-focused build, the motherboard is more expensive than necessary, but it’s still a reasonable match for your components. A cheaper B650 or B850 model with good power delivery, adequate M.2 support, and the connectivity you actually need would be the practical choice. Keep the X870-E-H if you like the board and don’t mind paying for its features; just verify the M.2 and PCIe lane-sharing behavior before finalizing the build.
It’s a perfectly capable board, and ASUS boards have generally worked well for people with similar Ryzen gaming systems. The main concern is price: for mostly gaming and normal productivity, a solid B650 or B850 board around $150–$200 would deliver essentially the same performance. At $300, the X870-E-H makes more sense if you specifically want its extra connectivity, USB4, expansion options, or simply prefer its design and features.
One thing to check before installing both SSDs is the motherboard’s lane-sharing layout. Using the second M.2 slot can reduce the graphics slot from its full link width, potentially running the GPU at x8 instead of x16. That usually has only a small real-world impact, but it’s an annoying limitation on a premium-priced board. Read the manual carefully and use the M.2 slots that preserve the GPU connection where possible.
The extra USB ports aren’t important to me, so value is definitely what I’m trying to figure out. I mainly wanted a reliable board for the 9850X3D and RTX 5080.
