Are you really surprised i can run 3 monitors? I am not being sarcastic. My 2080 super is running 99% at 67 degrees while 3 monitors are running (3840×2160) (60hz each). Granted, i have not pushed a high frame rate game yet either, except with my Valve Index. Now that is the reason i want two video cards, because i can reach 144 FPS with the index if i have the GPU power to do so, hence my thoughts of chaining cards, the dilemma i have is, my tower is too small to have the appropriate cooling and air circulation (mid tower). This is why i want a full tower case for xmas from the wife, and the samsung 2tb M.2 drive. We will see. LOL, ( or ill just buy them myself.
After that is all built, then ill buy the 120hz Monitors
