When it comes to getting real work done, there’s still nothing to compete with a laser printer’s combination of quality, speed and economy. We tell you how to choose a busines laser, plus review 3 examples.

From personal printers to home office colour, we put 12 lasers through their paces. Some are lightning fast; others produce dazzling colour. Some are tiny, and some are surprisingly cost-effective.

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.

With so many factors to consider, choosing a motherboard can be a bewildering exercise. We put 11 models through their pace to find the ultimate in performance, flexibility and value

TCO, or total cost of ownership, is virtually a mantra when it comes to volume printers. Unlike other peripherals, like monitors or scanners, the initial purchase price of a printer represents only a small proportion of its overall cost over its lifetime. Consumables, like toner and replacement image drums, add to the cost, and some printers with low initial purchase prices can easily turn out to be significantly more expensive than more pricey units, after a couple of years.

All the power of a desktop PC in a fraction of the space. We put a selection of desktop replacements to the test.

Unlike many of our performance-based Labs, business workstations are a whole different world of PCs, focusing not on the maximum number of frames per second, or how many overall points they can churn out in any given benchmarking utility.

Benchmarking PCs is a tricky business. You need to ensure that you stress the systems, but also that the results you get will be relevant in the real world. Previously we have relied heavily on BAPCo's SYSmark2002 for simulating home and office use, with programs such as Excel, Word, Outlook, and web content through Adobe Premiere and Macromedia Dreamweaver. However, due to SYSmark's history of instability as well as the sheer length of time it takes to complete a run, we have put it on the backburner in favour of PCMark04 for this Labs.
