Asus P8Z68 Deluxe Gen3 Motherboard Review

A new feature we are adding to all of our motherboard reviews is what we call the Ninjalane Mulit GPU Index.  The Multi-GPU index is a portable set of data we can apply to determine the multi-gpu potential of any motherboard.  A higher index number indicates a favorable condition for multiple graphics cards while a lower number indicates a hindrance in one of our leading indicators.  Since the Index does not take into consideration system architecture it can be applied to motherboards regardless of processor or chipset generations.

Index:  3.25
Optimized: 2x
Max Support: 3x

NVidia SLI
AMD Crossfire

This motherboard will support up to 3 graphics cards but, as we indicated, is optimized for dual card operation.  Given the minimal multi card support there is no need for any additional PCI Express power.

PCI Express 3.0 support is made possible by the use of a single PLX bridge chip located under the first video card slot.  This bridge chip serves the added benefit of allowing you to run more PCI Express devices by splitting up the available lanes and dividing them up differently.

For best video performance you will want to populate the top most PCI Express slots with video cards,  Given the distance between the slots you'll need to use the included SLI bridge or make sure your Crossfire connector is long enough to reach.
