I am probably forcing my cpu to render my 10 sec videos and What if I use 8gb with another 16gb (total 24GB) same power as my old 8gb ram, and should I buy the gtx 1660 super?
IMO, just another 8gb will be fine. You'd be able to run in dual channel mode then (I'm assuming you have a single stick right now). A 1660 super would go well with your build and allow you to upgrade your CPU in the future as well.
