Neither.
PC gaming just got a whole lot more interesting with AMD actually stepping up. No point in paying $500 + tax with a gaming specific system. I'd rather do a rebuild (probably $2000-$3000 or so) of my PC since it's my work, play, and sim system.
Already have a decent ultralight work laptop and no interest in a desktop or large gaming rig. I used to play on PC but console gaming is just more convenient
