Question can a Radeon R5 graphics card be upgraded in a dell Inspiron 3688 desktop?

  1. The Integrated graphics R5 can not upgrade.
  2. You can upgrade the PC by installing a dedicated graphics card, GPU. But make sure you may upgrade the PSU too, it depends on which GPU you will buy, because usually the OEM PC, like your dell PC, has only 300W PSU.
  3. One more, I can't find the dell Inspiron 3688. Inspiron 3668 is intel PC, Inspiron 3655 is the AMP PC.
