We test nine devices, from the simplest printers to versatile multifunction devices that print, scan, copy and fax

How much notebook will $2500 actually buy you? The PC Authority Labs team investigates.

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.

Before widespread use of the Internet, computer viruses were not a common occurrence. Viruses could only be transferred via floppy disk, which meant that it was quite easy to guard against them

The Labs team cuts through the jargon and tests next gen wireless products.

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.

Finding a good PC or notebook for the family is not as hard as you might think. PC Authority  puts the latest models to the test.

We put every current model from ATI and NVIDIA through its paces to find out which offers the best performance and value.

We know you want to play games, so we've put 18 PCI Express graphics cards under the microscope to see who really does the job the best.
