This is my build but the only difference is I have a RX 470 4GB GPU and im about to buy either the 1660 ti Ventus or 2060. Just asking if the 2060 is worth the extra money! Please respond fast and thank you :)

It will ultimately depend on your monitor. Presuming you will not be upgrading the monitor you used for the RX 470, the 1660Ti will serve you well and will offer a nice bump. Just be sure you are not gaming on a 1080p/60Hz monitor, if you are, the 1660Ti will offer little improvement over the RX 470 outside of higher benchmarks / frame count numbers.
