I would go back to PC. I buy consoles for the exclusives (why I have all 3 now) and two of those consoles will feature every big PC game in its library as well. That said, I see no reason to continue investing in a powerful PC (I would go all out just for shits and giggles) when I already have consoles that play most of the games already.
If exclusives were not in the equation, I would go strictly PC for the steam deals if not the performance boost. Make no mistake, exclusives are the ONLY reason home consoles are not going anywhere anytime soon.
