Want to upgrade my computer for this game, need some advice.

I dunno. While expensive the build is pretty solid. Gotta appreciate that Quad Channel DDR4 and I bet FFXIV would be smooth as butter running 120 FPS on the TV

For streaming and other programs where the cores will be used yes, but your every day gamer would never utilize the extra cores, a better choice would be either 4790k or 6700k which performs better in games.
