Once we've purchased a new PC most of us will intend on using it for a couple of years before upgrading or purchasing something new. When it's time to upgrade most manufacturers have improved hardware significantly but you still need to consider what your needs are, and what upgrades will be most beneficial. By choosing the correct upgrades for your specific needs, whether gaming, video editing or browsing the web, you could improve your systems performance in those areas significantly.16 Oct 2008
