Please be aware that this is a first look at Intel's X38 chipset and as such we are not running the full suite of benchmarks, overclocking or stability testing until we receive a final retail samples. Both the BIOS and board we are using are engineering samples, so performance may improve with both retail board and BIOS revisions.

The nForce 680i SLI is still based on DDR2 and at 800MHz 3-3-3-9-18-1T its performance is generally still better than 1,333MHz DDR3 memory at 7-7-7-20, which is somewhat surprising on one front, but expected on another. Gigabyte's X38 board is still fractionally faster than the Asus P5K3 Deluxe in Everest though. The Sandra scores show the other end of the scale, with the average DDR2 score coming out far slower and the Gigabyte losing out ever so slightly to the Asus P35 board.
