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.

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.

Legend QDI

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.

The processor struggle continues between AMD and Intel as the war rages on for the top ranking of the market share table. Interestingly enough, of the four machines this month under the $2,500 price tag, Scorpion Technology's Z-Box was the only unit to feature an AMD Althon XP processor. Also interesting was the marginal gains achieved by Intel given their obvious clock speed advantages over this unit.

Although the mobile marketplace has been changing in the face of Centrino and the slow but gradual tablet PC adoption rate, large form factored (greater than single spindle) notebooks are still the order of the day.

Despite the processor industry being driven for so long by the now dispelled 'Megahertz Myth', AMD's budget conscious 1.833GHz Sempron 2600+ CPU put in an very good showing.

Small form factor (SFF) PCs now have their foot well and truly in the home entertainment and IT/CE crossover market due largely to their aesthetics, functionality and quietness of operating volume. Westan's Biostar product looks to continue along these lines, offering a multimedia PC with all the performance of AMD's 64-bit desktop processor architecture.

If your PC is less of a speed demon and more of a dinosaur then it's time to upgrade your CPU. We put the latest low, mid and high end processors to the test.

Another notebook to embrace the entertainment market and sell units with widescreen 16:10 aspect ratio displays, this PowerNote packs some serious hardware under the hood, pushing not only AMD's Mobile Athlon 64 3200+ processor, but also ATI's Mobility RADEON 9700 a 60GB, 7200rpm hard disk drive and a multiformat 4-speed DVD burner for disc creation on the go.

While AMD has been waving hybrid 32/64-bit CPUs for some time now, speculation has risen over when Intel would unleash their product onto an already expecting market. Here it is, Intel's newest addition to their Extreme Edition clocking in at an impressive 3.73GHz and boasting a 2MB L3 cache.

While the Celeron's history is dotted with major successes, like the legendary Celeron 300A and overclockability, the name has remained a budget brand. Comparatively the CPU lacks features, with only 128KB of L2 cache to AMD's 256KB.

Very narrowly pipped for the top placing Labs winner award this month, Plus offers an impressive performing gaming machine with all the bells and whistles you'd expect to find at this price point. Wrapped in the attractive Cooler Master Cavalier wave housing, there's no ultra portability to be found here. The clear advantage of moving away from small form factor housing is not being starved for space internally.

The first PC Direct machine we've tested features an eye-catching black anodized case with custom stealth drive face plates on all drives and front USB and audio connectors. Easy access via the tool-less snap panels takes this case the extra mile.

Synonymous with cost effective CPUs, Intel's Celeron has carved a market for itself by producing products which are reliable and boast something many others cannot – interoperability. This has been achievable by producing products that work with the same socket 478 pin configuration found across the entire range of processors.

It’s one of the facts of the gaming hobbyist’s life: cutting edge games require cutting edge hardware. It’s as set in stone as Moore’s Law (which is itself now 40 years old). Every 12 to 18 months you need to upgrade or get left behind. Our contenders this month make a very good case for starting with a clean slate, and none more so than this month’s winner, the Modtech Civic-64FX.

When we sent out the call for multimedia systems we were expecting notebooks and PCs capable of DVD playback and some basic gaming. Pioneer not only cleared this bar with their submission - they raised it.

The world is Paragon City, in which costumed heroes patrol the skies or walk the streets.

We love hardware. As users ourselves we feel your pangs of wanting the newest, fastest rig and components. Unfortunately it's hard to justify the cost of bleeding-edge hardware at the best of times - more so with the cost of single graphics cards at times exceeding the $1000 price barrier. This is as much as some users would spend on a total system upgrade.
