NVIDIA is sticking to using only NVIDIA approved vendor list (AVL) components for their 680i series of motherboards. These components include capacitors, resistors, oscillators, and field effect transistors. They are designed to ensure high-quality components are being used throughout the entire manufacturing process for better QC control. Qualities in means quality out when it comes to the components you use building your personal system, and NVIDIA aims to please.

All of NVIDIA's 680i chipset motherboards are based on the six layer design used for enhanced quality and better circuitry protection. The normal motherboard design places the signals on the top layer, followed by layers for power, ground and more signals. The 6 layer design adds two additional signal layers in the middle of the Silicon, allowing for more optimized power delivery to the components and a more electronically stable motherboard. EVGA utilizes a black PCB that is eye catching and good for custom build systems where you will see the board.

NVIDIA also introduced LinkBoost with their AMD nForce 590 SLI motherboard last year. This automatically increased the PCI Express bus speed by 25% over the default 100MHz clock when a compatible NVIDIA video card was installed (7950 GX2 or later). With the 680i this has moved to the Intel chipset platform, allowing for up to a 25% increase in bandwidth from the video cards to the system. This will also be beneficial when running the system in SLI Mode. Another innovation of the nForce 590 that was carried over to the new 680i chipset was the introduction of EPP memory support. Enhanced Performance Profile memory stores additional information in unused data bits beyond the standard SPD information including the memory voltage and command rate of the memory. Profiles can also be set, to allow a wider range of settings for a particular memory chip. SLI supported memory is an option that AMD and NVIDIA worked on at its launch and is now transferring over to the Intel platform. This was not only technically a brave move, but marketing genius as well.

NVIDIA's nForce 2 chipset was the first commercially available and viable motherboard to support dual Ethernet right out of the box without the need for an adapter. The release of the nForce 590 SLI chipset introduced DualNet technology, allowing the two LAN ports to do things like teaming, load balancing and fail-over along with TCP/IP acceleration. Teaming turns the two Gigabit Ethernet connections into a single 2-Gigabit connection. TCP/IP acceleration accelerates traffic processing. FirstPacket technology allows the user to set priorities for the upstream bandwidth. If a game or app needs more, you can set a priority with FirstPacket giving it more bandwidth. The 680i moves NVIDIA into the next technical level in some aspects of its design and has all the best from its past experience built into their new chipset as well. The 680i series of motherboards are all supposedly able to be flashed to new BIOS update that allows the use of Intel's latest 133MHz CPU line. The only thing that is pacing this chipset series of boards is the introduction of lighting fast DDR3 that even though pricey at the moment will eventually be the new way of technical advancement. Intel's P35 and new P38 both support DDR3, and overclockers will eventually see there way down that road.
