To best determine the overclocking capabilities of these high-end AMD 790FX + SB750 chipset motherboards, we brought back MSI’s K9N2 Diamond, which is based on the highly competitive nForce 780a SLI chipset from Nvidia.

AMD sent its fastest Phenom X4 processor, the 2.60 GHz model 9950 BE, for us to use in our motherboard overclocking and performance evaluation.

Overclocking doesn’t have much value if the rest of the system can’t perform, so we also ran our standard set of performance benchmarks.
