A:Answer You can, but you would need to upgrade the power supply, and install a dedicated graphics card. It would depend, though, on which PC games you wish to play.
I just replaced my 12 year old Dell with this model. I had a more powerful power supply, and a low end graphics card installed. I still had to use low to medium settings on some games.
I can actually run those games better on this computer--without adding a card . I think a lot of games were harder on the processor (s) and RAM, and the card wasn't the culprit. This one has a lot of RAM, and a bunch of newer processors.
