Wow, I'm impressed to see there's still some others using a 5820K! Though mine is nowhere near as overclocked as others. I just did a minimal increase from it's base 3.3GHz to 3.8GHz.
Although I am trying to figure out why everyone is advising I get a newer GPU than the RX590? I only bought it last month! Lol. Fair enough it's not exactly new tech. But it'll tide me over til AMD release whatever they plan to release after the RX5000 range. And it's been totally fine with the games I have played on it: Star Wars Fallen Jedi Order, Modern Warfare, Battlefront II, etc. Even had them on max settings.
Still running mine, ticks over at 4.2 and paired with a 2070. Occasionally I look at an upgrade but always after looking into the numbers, it doesn't make any sense.
