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.
