PowerColor X1650 XT 256MB AGP Video Card
 

The PowerColor X1650 XT 256MB AGP Video Card breathed some new life into a solid system that really only shows its age due to AGP graphics being featured. Performance in benchmarks and many games was better than expected, and showed that there really is no reason to retire a system simply due to the fact that it doesn't support PCI-Express.
