HP Quadro P400 Graphics Card

Good for speeding up photo editing.

This is a half-height, half-length card that fits a compact desktop. I chose it because it adds a relatively modest 20 W to the PC's power consumption. It noticeably speeds up some photo editor image loading, so it is an improvement over the integrated graphics in the PC. But, you may have to upgrade the graphics drivers, and the process for finding and selecting those drivers is poorly documented. This was sold as an HP part, but the HP web site the instructions sent me to was essentially useless, and Nvidia's only a little better.
