I have a gaming PC which has more power than PS4. But I also have a PS4 because I love many PlayStation exclusives. I also have an XB1 which I bought for the exclusives though its exclusive library is dwindling and Satya Nadella's recent statement gave me no confidence but ah well I have already bought it.
As long as Quantum Break and Gears Of War 4 are great games and not on PC, I'll be satisfied with my purchase of XB1.
