I ran a very similar set up before upgrading to a 2070. I had a Ryzen 5 2600 @ 3.7 GHz with a 1660TI and 16 gigs. The base freq on your CPU is fairly low, so I don't know if it compares well to my CPU or not, but I could run my system at around 30FPS mins with view distance set to 4-5k on foot and everything else at Ultra or very high.
