New build. Totally overkill, I know.
i7 5820k with a light overclock at 4.2 GHZ
16 GB DDR4 RAM at 2400 mhz in quad channel mode
650W fully modular PSU boasting 92%+ efficiency
2 SSDs and HDDs (cause I took the ones from my old build to my new)
Fractal Design Define R5 case
And using my old Filco Ninja and a Logitech G700s for peripherals.
