I would take the 2 scenarios you have come up with and find benchmarks out there. Usually the cheaper of the choices people put is the better because its cheaper, both setups up there are going to be good for gaming, esp if thats just what ur doing, but intel usually has the edge on gaming performance, but its not always the case if that performance gain is like 100 bucks or more, so if i had to choose itd be the amd one up there for being cheaper. Also, if you dont mind not having rtx, then you can get the 1660, but youd have to go with ur first choice if you want it no matter what.
