10 Best Motherboards 2025 in the United States

The Biostar N68S3B is a micro-ATX motherboard designed for older AMD Socket AM3 processors like the Phenom II and Athlon II series. It supports up to 8GB of DDR3 RAM across two slots, which is sufficient for basic computing tasks but may be limiting for memory-intensive applications today. This board features an nVidia MCP68S chipset, offering decent stability but lacking modern features found in newer boards. Expansion options include one PCI-Express x16 slot for a graphics card and one standard PCI slot, suitable for adding extra cards like sound or network adapters, though it does not support multiple GPUs or very high-end graphics setups.

For storage, there are two SATA2 ports with RAID 0 and 1 support, allowing basic data redundancy or speed improvements, although the SATA2 interface is slower compared to current standards. Connectivity includes eight USB 2.0 ports, PS/2 ports for older keyboards or mice, a VGA video output (without HDMI or DisplayPort), and a standard Gigabit Ethernet controller. These features cover essential connections but lack modern USB 3.0 or faster networking options. Audio is handled by a VIA 6-channel HD codec, providing decent sound for everyday use.

This motherboard is best suited for budget builds or upgrading older systems rather than building a new, high-performance PC. Its BIOS/UEFI features are basic, reflecting its age. The Biostar N68S3B is a solid choice for those needing a simple, reliable board for legacy AMD processors but who can accept limitations in expandability, connectivity speed, and modern features.

The Biostar MCP6PB M2+ is a micro ATX (MATX) motherboard designed for AMD processors using the Socket AM2+ and AM2, supporting a range of CPUs including AMD Phenom II, Athlon 64, and Sempron. It features the AMD 785E chipset paired with NVIDIA GeForce 6150 / nForce 430a, which was solid for its time, providing basic integrated graphics and chipset functions. You can install up to 4GB of DDR2 RAM across its slots, running at 800 MHz, which is quite limited by today's standards but was typical for motherboards released around 2004.

This board supports HyperTransport technology for faster communication between the CPU and other components, and it is recommended to use CPUs with a TDP of up to 95 watts. Expansion and storage options are basic, fitting smaller builds or budget setups, and connectivity is standard for older systems, without modern USB 3.0 or M.2 slots.

The BIOS/UEFI is traditional and simple, suitable for basic configuration but lacking advanced features found in newer boards. This motherboard is best suited for older AMD systems or users looking to maintain legacy hardware rather than building or upgrading a modern PC.

The Biostar MCP6P M2+ is a budget-friendly micro ATX motherboard designed for AMD processors using the AM2, AM2+, and AM3 sockets. It supports a range of AMD CPUs including Phenom II and Athlon models, making it suitable for older or entry-level setups. The board uses the AMD 785E chipset and supports DDR2 RAM at speeds up to 800 MHz, which is outdated compared to modern standards but appropriate for upgrading or building a system with older parts.

Its micro ATX form factor allows it to fit well in smaller cases, which is convenient for compact builds. Storage options are limited to older SATA connections without support for the newest SSD interfaces. Connectivity features are basic and may lack modern conveniences like USB 3.0 or integrated Wi-Fi. The BIOS/UEFI likely uses a traditional BIOS with limited features relative to current systems.

This motherboard is a solid choice for running or repairing a legacy AMD system when the latest technology is not required. Users needing modern performance, faster memory, or expanded connectivity may find this board limited.
