Thought: do we want to set up a recommended MKX PC build for anyone else interested in making that move? I know there's a lot of people increasingly and reasonably disillusioned with Sony and MS.
The thing is, hopefully if you're building a PC, it won't just be for MKX. There's so much goodness on Steam, and a lot of top-tier games are going straight to PC Day 1 nowdays.
For an MKX + whatever else config, I'd probably want to recommend:
-i5 (don't blow the money on i7 unless you need it, usually for something other than gaming)
-GTX 970 (best performance value for the money, and also near-future-proof)
-8 GB RAM
As far as the SSD, it makes a huge difference in booting your OS, and also if you're working with large files (video, Photoshop, or playing big RPGs that load enormous maps, like the Witcher III), but you likely won't see that much of a difference for fighting games and smaller gametypes, so it's optional.
