Congrat's jedi95 on your Billion! Are you folding on the GPU's you pictured in a post awhile back? {older series} If so that's pretty darn good. :)
I'm using most of those GPUs at this point. I decided against running the R9 290X and GTX Titan Black 24/7. These cards just use too much power for the work they do. I'm also only running my highest core count CPUs because all the lower end ones are just awful for PPD/W.
My farm currently consists of:
CPUs:
Threadripper 3970X
Ryzen 9 3950X
Nvidia GPUs:
RTX 2080 Ti
Titan X Pascal
GTX 1080 Ti
RTX 2070 Super
RTX 2070
GTX 1060 6GB
GTX 1650 Super
AMD GPUs:
Radeon VII
2x RX 5700 XT
RX 5500 XT
Vega 64 Liquid
Vega Frontier Edition
RX 480
Most of these cards are undervolted at stock clocks. The exception is the RTX 2080 Ti in my main system which holds 2100MHz core pretty much constantly.
