TDS Liquid

Hey there, I'm new to the community which I found through Linus youtube channel. I have a PC I built about three years ago and wanted to get some more performance out of it. I use it to stream mostly game. This is my current build CPU: i7 4790k @4.0ghz Mobo: ASUS ROG Maximus Hero VII GPU: MSI GTX 980 PSU: Corsair hx850i Cooling: Corsair h100i Monitor: Acer Predator XB2 (240hz@ 1080p) I was planning on replacing my GTX980 with either a 2070 or 2080, itd like to play my games on Ultra settings with much better frame rates. If someone could post an ops thread that maybe goes in depth on how to OC or if you might have some suggestions as to what programs I should use to stress test and a little insight on were to start OCing, its appreciate any information!
