A PC can start to show its age when the components installed start to slow down or are unable to keep up with newer software and games. Perhaps you built a desktop PC for light computing and are now needing a machine for video editing, which requires additional performance. This is what makes a desktop PC an excellent device as it can be upgraded at any time with new parts. The question is: which part do you upgrade first? The correct answer is … it depends! If you need better gaming performance, it will likely be the GPU. For running more apps, I would recommend upgrading the RAM.
