If we take it in a literal sense then just the sheer cost to maintain a gaming rig will make it impractical in the long run(this is assuming that you are planning on gaming at the best performance possible, uncommon sure....but still) You would have to constantly upgrade, which would cost you thousands every year. A console may not have that option, but only requires software updates. Its easy to plug in, play and relax. With k&m support, you can play at peak efficiency as well. If we take it in a literal sense, then pc would be more expensive.
