Which is more important - Interconnects or PCs?

If your system is up to it, the right Power Cord would make the biggest improvement.
Then interconnects from source, and interconnects to Amps.
Speaker Cables last.
IMHO

Any path that carries the signal i.e. interconnects or speaker wire, will be affected more by wire changes than a power cord. That's quite basic.

In addition to getting other enthusiasts opinions which can be useful but usually conclude little, wouldn't it be a good idea to also consult the manufacturer of whose cabling your using or interested in and let them give guidance specific to their product? There is rarely a broad brush stroke answer for such a specific situation. Broad brush stroke answers have contributed to some of the confusion and wasted efforts most of us have experienced.

Just a thought. Don't slug me.
