While 64-bit computing has been around for a while (for the two of you who could afford Intel's Itanium, and now Itanium II processors), the dream of 64-bittery for the humble home system has been a long time coming.

The FX-55 is AMD's top performer. It's a 2.6GHz beast that will eat through current and future games and applications. Its architecture is based on that of the FX-53, which in turn was based on the first generation FX-51, and AMD has come a long way in bringing 64-bit to the desktop.

The Athlon XP 2700+ represents a significant leap forward for the Athlon line – it solves a long-term problem by stepping up the default frontside bus (FSB) speed from 266MHz to 333MHz. This means that the Athlon XP can finally run in sync with 333MHz DDR RAM. While most currently available Athlon motherboards support 333MHz DDR, there is virtually no performance boost between this and 266MHz DDR when running an Athlon XP with a 266MHz FSB. The extra speed offered by the RAM quite simply goes to waste, because the CPU can't keep up with it.

In the performance stakes the 3200+ came up trumps, finishing middle to top of the pack and clearly cementing itself as a solid performing processor for home, office or pure entertainment.

VIA has dominated the AMD arena the last couple of years, and its latest offering is the KT400 chipset, which despite its name, only officially handles DDR333 memory. Many boards however do have limited support for DDR400, as well as AGP 8x.

The nForce2 is the only dual-channel memory controller available in the AMD pantheon. There are two Northbridges to choose from: one with the Integrated GeForce4 MX-class graphics (nForce2 GT) and one without (nForce2 ST). Both offer support for AGP 8x and up to DDR400 memory, although we recommend you use DDR266 or DDR333 memory in synchronous mode (DDR266 for chips with a 266MHz FSB, DDR333 for those with a 333MHz FSB) for best performance.

Legend QDI

ABIT's new NVIDIA nForce2 motherboard, the NF7-S, supports the AMD Duron, Athlon, and Athlon XP, and also features dual 400MHz DDR memory controllers.

The Athlon XP 3200+ will probably be the last Barton-core desktop processor to come from AMD before the launch later this year of the Athlon 64, its desktop 64-bit processor.

Clever corner cutting gives us an affordable, upgradeable performer.

The creme de la creme of Athlon 64 products, the 4000+ is a socket 939 CPU with all the bells and whistles. This bad boy clocks in at 2.4GHz, features a 1MB L2 cache and 2GB HyperTransport memory interconnect to work in conjunction with its on-die memory controller.

Another inexpensive Soltek board that's not too heavy on the features, this KT400A board sports the bare minimum to scrape by, with six-channel audio, dual-USB 2.0 ports and ATA133 support.

A barebones Athlon mobo, the AK39N has enough functionality to set this board apart as an ideal platform for building a home PC or workstation.

A board with middle-of-the-road features, the NF7-M boasts a well-designed and spacious layout with some nifty additions.

The MSI K7N2 is a good nForce2 board overall, scoring well against other nForce2 contenders.

This is one of the few nForce boards here to take advantage of the GeForce4 MX graphics chip and supply an AGP 8x slot.

Like the AK39N, the AB48N is a slightly smaller ATX board with two DIMMs, and does not come with SATA, although it does incorporate six-channel audio and 10/100 Ethernet.

The WinFast K7NCR18G-PROII has a well -rounded set of features, and besides the ABIT NF7-M, it is the only Socket-A board in our round up to offer support for a front side bus speed of 400MHz.

Well and truly gone are the days of boring green and brown PCBs – and welcome to the yellow motherboard, care of Soltek.

For it's price, the 7NNXP has the usual set of features, and offers IDE RAID but no SATA RAID.
