I dunno mate. I still believe we will see a rapid increase in the availability of supported AAA titles on Steam.
Either way, I suspect Timey will have an enviable machine like
this one.
And he'll still have his PS4, which with 8 x ACE should see some big improvements when developers really start to take advantage of multi thread game structures. XBone may struggle there as I believe it only has two. I wonder if Sony knew this when they customised their (effectively the same as the Xbone's) APU? They are part of the Kronos group, while MS perhaps had DX12 aspirations in mind instead.
It will be interesting to see how it plays out over the next 18 months.
