The motherboard supports the AMD RYZEN 7 3700X, but you'll need to upgrade the BIOS. It's possible to install it without major issues, though checking compatibility and ensuring proper installation is important.
Without a heat sink on the motherboard, an uncovered VRM limits performance for high-core processors. A Ryzen 5 3600 would be a better fit for that setup.
League of Legends, Overwatch, World of Warcraft, Heartstone, Dead by Daylight, BFV, Diablo, Rocket League—aiming for 144Hz max settings in the 2060s sounds like a solid target.
I'm not sure if overwatch and battlefield 5 will reach consistent 144fps with that CPU, but those games will benefit from the extra horsepower of the 2070. Wow, hearthstone, rocket league, league of legends, all super easy to run at high refresh rates. Edited May 1, 2020 by Fasauceome
I asked in the Discord server, they said it should work fine as long as you don't overclock it.
You mentioned you've already boosted the overclock, so perhaps it's too late for that. If you're new to checking VRM temps, you could be causing your motherboard to overheat.
