As expected, getting the PCIe video card out of the Z820 was akin to stealing treats from an infant.

The card HP dropped in our loaner box isn't much to write home about, but the upgrade potential is pretty great.

Users can install their own PCIe graphics card, or configure their Z820 with one of several different AMD or Nvidia cards.

So to recap, that's an easy to upgrade card with a wealth of compatible options now and in the future. Not looking so great right now, Mac Pro.
