This refurb Dell Optiplex gives me performance rivalling many new PC's.  Intel quad-core architecture, ample memory and an industrial grade mobo deliver solid,  lightning-fast  responsiveness and multi-tasking capability to satisfy almost any power user.  Though not a gamer's machine with mind-blowing graphics, it delivers outstanding performance in the ways that matter for a chump-change price.  The Microsoft-approved refurbishment gives me confidence that  this machine will serve me well for years to come.  When it's time to upgrade, I'll look to this vendor first, who offers a wide array of desktops and laptops to fit the needs and budgets of just about anyone.  Color me happy & satisfied.
