The above table pretty much sums up the whole story. With the prices and offerings from each of the 3, it is a no-brainer which one to pick. On the same price level as the ASUS, the Gigabyte beats it with better overclocking in FSB and PWM, and way better voltage options in BIOS. For USD$ 10 more buying the Gigabyte over Abit, you get better overclocking in FSB and PWM, and better voltage options in BIOS. There is no consideration when one is looking for a 650i SLI board - The Gigabyte is the choice!

The Gigabyte GA-N650SLI-DS4 would be closer to perfection with a BIOS update so that it will be able to recognize a 266FSB strap via the LGA BSEL setup. This will help the E4300 overclock better. We have already seen it's amazing overclocking capability with the 266FSB processors. The performance of the board is so close to it's competitors, the hairline less than 1% difference will not be noticable. The overclocking on this 650i board puts even many of the 680i boards to shame...
