Choosing among CPUs, motherboards & memory gets complicated when four boards point to different processor sockets, memory generations, and Dell desktop systems. The useful shortcut is to match the platform first, then weigh form factor, condition, ports, and the features that matter to your upgrade. These four choices range from a used MicroATX Intel board to a certified-refurbished ATX AMD board, so the lowest price is not automatically the right fit.
Quick take
- Lowest listed price: ASUS Intel PRIME H310M-A R2.0, for an Intel LGA1151 and DDR4 setup.
- Dell XPS 8940 fit: Dell XPS 8940 motherboard, identified for 10th- and 11th-generation Intel Core processors.
- AMD AM5 route: ASUS ROG STRIX B650-A GAMING WIFI, with DDR5 support and ATX form factor.
- Dell Precision 3650 focus: Dell Precision 3650 Tower motherboard, with BIOS Unlocked and Computrace Unlocked listed.
- Price spread: The lowest and highest listed prices are separated by $117.62, reflecting very different platforms and system contexts.
Listed-price comparison
| Product | Listed price | Price bar | Key platform details |
|---|---|---|---|
| ASUS Intel PRIME H310M-A R2.0 | USD 43.96 | Intel LGA1151, DDR4, MicroATX | |
| Dell XPS 8940 Desktop Motherboard | USD 161.58 | Intel LGA1200, DDR4, XPS 8940 | |
| ASUS ROG STRIX B650-A GAMING WIFI | USD 124.99 | AMD AM5, DDR5, ATX | |
| Dell Precision 3650 Tower Motherboard | USD 89.99 | Intel LGA1200, DDR4, Precision 3650 |
Decision matrix
- Choose by socket: The ASUS PRIME is the LGA1151 route; the Dell XPS 8940 and Dell Precision 3650 boards identify LGA1200; the ASUS ROG STRIX uses AM5.
- Choose by memory generation: DDR4 is identified for the ASUS PRIME and both Dell boards. The ASUS ROG STRIX identifies DDR5 SDRAM.
- Choose by condition: The ASUS PRIME and Dell Precision board are used, the Dell XPS 8940 board is new, and the ASUS ROG STRIX is certified refurbished.
- Choose by system context: The XPS 8940 and Precision 3650 boards are tied to named Dell desktops, while the ASUS boards are described around Intel LGA1151 or AMD AM5 platforms.
- Choose by standout feature: DVI and VGA appear on the ASUS PRIME; up to 128GB memory is listed for the XPS board; M.2 and PCI Express expansion appear on the ROG STRIX; unlocked BIOS and Computrace settings appear on the Precision board.
Product notes
ASUS Intel PRIME H310M-A R2.0 LGA1151 DDR4 mATX Motherboard + I/O Plate

At USD 43.96, the ASUS Intel PRIME H310M-A R2.0 is the clearest choice when the target is an Intel LGA1151 desktop and the price matters. DVI and VGA are the named display outputs, while MicroATX and two memory slots define its listed configuration. Those details give it a specific role rather than making it a universal pick. The main limitation is condition: it is used. The two-slot count is also important if your upgrade plan specifically calls for four memory slots. Choose the ASUS PRIME when the existing processor platform matches LGA1151; it is not the route for the LGA1200 Dell boards or the AMD AM5 ASUS board.
Dell XPS 8940 Desktop Motherboard Intel 10th 11th Gen LGA1200 DDR4 K3CM7 427JK

The Dell XPS 8940 Desktop Motherboard is aimed at a very specific replacement or system-matching decision. Its compatible model is the Dell XPS 8940, and the attributes identify 10th- and 11th-generation Intel Core processors with an H470 chipset. Up to 128GB of memory is listed, alongside USB, USB-C, M.2, SATA, PCIe, and headset connections. At USD 161.58, it carries the highest listed price here, which is the clearest limitation. The condition is new, but that does not make it a general-purpose alternative to the ASUS AM5 board. Pick it when the XPS 8940 context and stated Intel generation support are the deciding requirements.
Factory Refurbished) ASUS ROG STRIX B650-A GAMING WIFI AMD AM5 ATX Motherboard

For an AMD Ryzen 7000-series desktop, the ASUS ROG STRIX B650-A GAMING WIFI provides the AM5 platform and DDR5 memory path in an ATX board. Its listed expansion includes M.2, PCI Express x1, and PCI Express 4.0 x16, while onboard audio, dual LAN, and onboard video chipset are also identified. The $124.99 price places it between the two Dell boards and the lower-priced ASUS PRIME. The limitation is condition: it is certified refurbished. The title also specifies ATX, so it serves a different form-factor brief from the MicroATX ASUS PRIME. Choose it when AMD AM5 and the named DDR5 support are central to the build.
Dell Precision 3650 Tower Intel W580 Socket LGA1200 Motherboard NDYHG 0NDYHG

The Dell Precision 3650 Tower motherboard makes the most sense for a Dell Precision 3650 Tower-focused decision. It identifies an Intel-compatible platform, LGA1200 in the title, and DDR4 SDRAM in the attributes. BIOS Unlocked and Computrace Unlocked are the concrete differentiators to weigh if those settings matter for the intended system. At USD 89.99, it sits between the ASUS PRIME and the two higher-priced boards. Its limitation is the used condition and the named Precision 3650 context, which makes the choice more specialized than a platform-only comparison. Select it when the Dell tower match and unlocked settings are more important than choosing an AMD AM5 board.
Final recommendation by use case
For an Intel LGA1151 desktop, choose the ASUS PRIME H310M-A R2.0 because its socket, DDR4 designation, MicroATX form factor, DVI/VGA outputs, and USD 43.96 price align with that brief. For a Dell XPS 8940 using the stated Intel generations, the Dell XPS 8940 board is the direct match, despite its USD 161.58 price. For an AMD Ryzen 7000-series build, choose the ASUS ROG STRIX B650-A GAMING WIFI for AM5 and DDR5. For a Precision 3650 Tower, the Dell board with unlocked BIOS and Computrace settings is the focused choice. Match the socket and system first; use price as the final tie-breaker.
