Hi, I know this is an extremely old and very contentious topic. I do have the aforementioned FX-9590 and the ASUS 970 Pro Gaming, and I've had it for the past 2 months, and my apartment hasn't turned into kindling just yet.
I game with it occasionally, and apart from some stuttering, which can be a drag, you can game with it. I have Ghost Recon Wildlands, Battlefield 1, Wolfenstein The New Order, The Division, etc.,
That's not to say I don't have some caveats about this setup though. I got this combo as a stopgap for a Ryzen build, and it basically burnt out 2 ram dimms I had in it earlier, had to buy two new ram simms.
I can tell you it is a space heater (and I live in Florida, so it is very easily noticed), and even though I have a Corsair H100i v2, I kept it at stock speeds, since I really am considering either buying a 8350 or just saving my money and completing my Ryzen upgrade.
Here is my complete setup as follows:
CPU: FX-9590
Motherboard: Asus 970 Pro Gaming Aura
Ram: G.Skillz Sniper 16GB 2400mhz kit (8GB x 2)
Cooler: Corsair H100i v2
GPU: EVGA GTX 1060 SSC 6GB (Watercooled with a H55 and a NZXT G12)
PSU: Be quiet Dark Power Pro 11 850 watt 80+ Platinum
