RTX 3080 and a LG TV are the biggest upgrade I've ever had in gaming. I waited a long time to upgrade to a tv that can handle 120hz, low lag, gsync, 4k, HDR and a good panel. Playing story games with 70fps with Ultra settings in 4k DLSS in balanced mode (or slightly lower settings for more fps) is just incomparable to anything else I've played. Since I got Cold war for free with the gpu I gave it a try and was very impressed by the visuals. That game looks absolutely gorgeous and is a perfect showcase game of the tech (graphics, DLSS, RTX, HDR, 4k, 120hz, gsync and perfectly playable with a lapboard keyboard and mouse). Control looks great and has some specific places it flexes its muscles with the lighting and chaos but overall Cold war takes the cake especially for a quick showcase for friends.
Only with highly competitive 1st person shooters like Tarkov I switch to the monitor and if I'm doing productive stuff.
This change also made it easier to split my pc for multiseat gaming too, I plug a 2nd gpu in my pc, I play from the couch, my guest from the desk (instead of sitting next to each other on two monitors).
