Want to perform an extreme makeover of your system's motherboard, processor, memory or hard disk? We'll show you how.

We've put AMD and Intel’s new processors to the test, and there's one clear winner.

All the acronyms and obscure new technologies got you in a jargon jumble? Tim Dean busts it up to help us make sense of it all.

Performance per watt has taken a backward step, but it’s very fast with the right apps.

So you want to make yourself a new gaming rig, one that’s capable of playing Crysis at more than two frames per second, but won’t blow the budget?

Choosing a CPU for your PC isn’t an easy task. Here are our picks for budget, mid-range and high-end systems.

A world first on the desktop, Phenom is good but a long way from outstanding.

Impressive technology, but increasing cores doesn’t necessarily increase performance.

Curious to see what powers the Nehalem and Core i7 architecture? We reveal the tech behind the fastest Intel-powered computer on the planet.

We test AMD’s first quad-core processor for both speed and power efficiency

The move to a new platform brings credible new challengers to Intel’s Core 2 processors

AMD’s next generation of CPUs brings 45nm technology and higher clock speeds - but is that enough to compete with Intel’s latest and greatest?

A fast, quiet, good-looking PC that's great value.

Quad-core makes it powerful and good value at the price. Noise and stability suffer though.

AMD is likely to shift production of desktop CPUs to 45nm process technology by the third quarter of 2009 and launch several new CPUs, say sources in the know.

A smartly engineered processor, but for today’s applications it’s lacking in bang per buck.

Not very competitive on price, but there’s plenty of scope for performance

Nothing incredible in terms of design, but it’s an impressively cheap way to get quad-core in your PC.

Intel’s three new CPUs promise Core i7 power in an economical and efficient package. We put them through their paces to see whether small really is beautiful
