Today, we're going to test several of socket 939 PCI Express motherboards. There are four motherboards using NForce 4 chipsets are ABIT's AN8 Ultra, ASUS A8N SLI Deluxe, Gigabyte's K8NF-9, MSI K8N SLI Platinum. ABIT's AX8 3rd Eye is the odd man out with VIA K8T890. The SLI motherboards (A8N SLI Deluxe, MSI K8N SLI Platinum) may have the added advantage of SLI support (dual physical PCI-E x16 slots), but non SLI motherboards should be more affordable to users so don't count them out yet.
