id like to play at least 1080p 144fps on low settings
Your setup at the moment for the games you play is ok, if you want to play the upcoming cyberpunk I am 90% sure that you won't be able to do so at 144Hz , for $1000 you can upgrade your CPU+MOBO+RAM+GPU a fair bit, I will give you a suggestion that I think will be good for you, I don't recommend you upgrade only one part of the PC because the other one will be a bottleneck, this is my recommendation:
