While most of the above motherboards can be found in our previous reviews, Asus’ P6X58-E WS is new. The primary feature that differentiates it from the P6X58D-E is the addition of Nvidia’s NF200 PCIe bridge, which expands three-way CrossFire and SLI slot configurations from x16-x8-x8 to x16-x16-x16. Other important upgrades include the ability to support a total of five single-slot graphics cards, though single-slot cards will not be part of today’s tests.

By relying on a single brand of motherboard for all four samples, we reduce the risk that performance differences will be the result of BIOS or clock speed differences. Asus helped us keep the spotlight on its brand a little longer by sending along three of its GeForce GTX 570 graphics cards as well.

Of course we couldn’t let Nvidia’s cards stand alone. We borrowed our AMD Radeon HD 6950s from another project.
