And yes, I think it's perfectly reasonable that the PC is a superior choice for the enthusiast RPG gamer (I'd also add, though, if we were to look at releases in 2013, wouldn't the 3DS have the edge there?). Of course, many PC of the highest-profile PC RPGs from that list... aren't particularly demanding on hardware power anyway.
Besides that... I'm an enthusiast gamer. I don't specialise in a single genre. Where can I find the best platformers? 2D and 3D? PC's serving my needs for point-and-click adventures very well, I'm pleased to say. RPGs? Well, PC has a clear edge for RPGs in general, but JRPGs I think you'd be better off with a 3DS, or possibly a PS3, particularly in light of the forthcoming Persona 5. Driving? PC does okay for sims, but for more arcadey fare, I think the consoles have a better lineup, and for the sillier Mario Kart stuff there's no contest.
That's the thing: There's a *ton* of nuance, and just stating that the enthusiast gamer should pick PC because it's just Better is going to leave you with some - subjectively, of course - inferior options. Far better for the enthusiast gamer to go where the games they want to play are.
