EVGA nForce 680i SLI

Intel or Nvidia? nForce 680i Challenges Intel P965 and 975X
By

EVGA's nForce 680i SLI is a real enthusiast product; it comes with a powerful six-phase voltage regulator, a heat-pipe cooler for northbridge and southbridge, a built-in Port 80 debug solution for troubleshooting, on-board power-on and reset buttons, and as many as six fan headers.

It utilizes all of the chipset features, such the DualNet Gigabit ports, six SATA/300 ports (two of them bent by 90°), three x16 PCI Express slots for graphics and a possible 3rd graphics card (which can be used for additional display connectivity or a physics acceleration card), two x1 PCIe ports and two classic 32-bit PCI slots.

The King Of Overclocking: FSB1850!

Be sure to reduce the processor multiplier before overclocking your system speed that much! At the default x11 multiplier of the Core 2 Extreme 2.93 GHz, the processor would have to run at over 5 GHz - which it cannot do.

The overclocking options and margins are simply amazing. Whether you use Nvidia's nTune utility - which automatically searches for close-to-ideal overclocking settings - or you prefer to play around with the massive number of settings in the BIOS yourself, you have the powerful tools you need to squeeze a lot of extra performance out of your 680i board.
