On all applications I know about outside of audio (where instruments are used to verify effect), it is dedicated lines & power conditioning, period. That is the way I went for noise control on a wide variety of industrial equipment and for my home stereo.I never was able to detect any improvement from different power cords. Will not debate pc's with others, just my experience fwiw.
If you plan to eventually use a power conditioner I expect that you will want/need a minimum number of outlets and will be plugging several components directly into the pc. I'm running my system with a total of 4 outlets & I've got several components. It is nice to figure out a place to plug the non-sound garbage generators (e.g. turntable drives & etc.) that is not on your dedicated line.
Good Luck!
