TRENDING NOW: 10TB SSDs are on their way thanks to Micron and Intel's new 3D NAND

ASUS A8N32-SLI Deluxe Motherboard - Full Speed SLI *Exclusive* - Specifications

When nVidia first launched their dual graphics platform, it initially come under some scrutiny for only offering two 8x PCI-E ports. Many months later nVidia announced their nForce 4 SLI X16 chipset which offers two full speed PCI-E slots, each with 16 lanes. Today we've got a very exclusive look at the ASUS A8N32-SLI Deluxe motherboard. We closely examine the performance of the two different PCI Express port lane configurations to determine if it's actually worth upgrading to the new chipset or not!
