Game projects grow quickly, so M.2 slots for separate engine, project and cache drives help. Every pick has four or more M.2 slots, ordered from the lowest price.
Rankings weigh M.2 slots, wired LAN and wi-Fi as the makers state them; we did not test these motherboards ourselves, and if a maker skips memory type, the guide says so.

Also Consider1 of 5
ASRock B850 Pro RS WiFi
The B850 Pro RS keeps four M.2 slots and a 14+2+1 layout on a budget board, with Wi-Fi 6E.
Best for
- Buyers who want PCIe 5.0 M.2 slot.
Skip if
- Worth skipping when wi-Fi 6E rather than Wi-Fi 7 is a problem.
Why we like it
It leaves more money for the graphics card. On M.2 slot count it ties with the Z790 Pro RS, the B850 Steel Legend and the Strix B850-A at 4. It shares a wi-Fi 6E with the Z790 Pro RS; the B850 Steel Legend goes with a wi-Fi 7.
It shares 14+2+1 power stages with the B850 Steel Legend; the Z790 Tomahawk MAX goes with 16+1+1 power stages. It also offers a PCIe 5.0 M.2 slot. It uses AMD's AM5 socket, so it takes Ryzen 7000, 8000 and 9000 chips; a board built before a CPU's launch may need a BIOS update first, so check whether it supports BIOS Flashback. Check the manual for which M.2 slots share lanes with SATA ports or the second PCIe slot before filling them all.

How We Chose These Motherboards for Game Development
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- The figures behind the order
- We compared five boards on M.2 slot count, wired network speed, wi-Fi and power stages as the makers state them. These are research figures, not bench results: 3 of 5 picks leave out memory type.
- What every pick has in common
- All 5, from the B850 Pro RS to the Strix B850-A, state M.2 slot count, wired network speed and wi-Fi.
- Where the specs have gaps
- The B850 Pro RS, the B850 Steel Legend and the Strix B850-A give no memory type; the B850 Pro RS, the B850 Steel Legend and the Strix B850-A give no chipset.
- Price range
- At our last check the picks ran from the B850 Pro RS ($100 to $150) to the Strix B850-A ($150 to $250).
