If you’re currently in the market for a socket 939 motherboard, I’d like to suggest the K8N Neo4 Platinum. This nForce4 Ultra chipset based motherboard from MSI is a great example of a clean, well-built motherboard that’s available for a reasonable price.
The reviews from most hardware sites are very good for this motherboard, and it’s not hard to see why. MSI has put all of the nForce 2 Ultra chipset features in a clean, attractive board that has few layout problems. Even the packaging and documentation included with the product matches this level of quality, featuring a very thick user guide and tested hardware booklet, along with a large full-color poster pointing out each of the board’s ports and interfaces.
A solid performer at a reasonable price makes this an easy recommendation.
