This is my Ryzen 9 3900X build. Is there anything I should change in my parts list? I would prefer changes that don't involve raising the total price. I will be using this PC mainly for video and photo editing (with some casual gaming here and there). List: https://pcpartpicker.com/list/R4c9zN
For video editing, RX 5xxx parts aren't very good. I would opt to downgrade the 3900x to a 3700x and upgrade the gpu to a RTX 2060. The encoding time for the rtx2060 over the 1660 is fairly substantial, but anything above the 2060 is relatively minor.
Some bench marks: 1, 2
I would like you to upgrade the psu to a higher quality unit, but the pickings are slim atm.
