Here is my Dual GPU, Purple PC in the fishtank of a case the Lian Li PC O11 Dynamic.
CPU is overclocked from 3GHz to 4GHz
RAM is overclocked to 3466MHZ
RX580 is BIOS Modded
The second gpu runs all my monitors other than my main one. I also do crypto mining on pc so I use both gpus for that.
Ive got a very similar build in the same case but I have slightly higher performance parts (2700x and 2070). I only have one GPU tho. The build looks nice and clean with a descent upgrade path, nice work.
