Definitively, 8Go of RAM is the standard now. Forget 32 bits processor, and
use a 64 bits one. More memory can be better depending of tasks done in
digiKam, but it's not necessary.

4 cores CPU is the standard now. More cores will be exploited in digiKam,
not everywhere yet.

GPU is less important here, but in the future this will be different.
Typically, the OpenCV C++ layer is designed to use GPU for computation.
OpenCV is used at many places in digiKam, especially in face workflow. But
for the moment, the bundle that we provide disables GPU usage for stability
(we prefer stability over efficiency). Linux native package will enable
this support of course.

SSD, not over USB is the best solution. Don't forget that USB is also a
bottleneck. I recommend a native connectivity to storage devices.

Voilà

Best regards
