amd first build with a ryzen 7 3700x + 1660 super need help

[wassil]

Budget (including currency): 1000$

Country: 

Games, programs or workloads that it will be used for: pure gaming

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): first build i want it to last with the upecoming consoles,1080p60fps

 

hey guys its my first build, at first i was going to get a 3600 + 2060super or 5700 but since its my first build i don't wanna upegrade it anytime soon specially with the upecoming aaa games, 8cores consoles and iam on tight budget so i thought ill get a ryzen 7 3700x + 1660 super or Ti just to be safe on those 8cores and for now ill game on only 1080p60fps i think the 1660s/ti will do the job.

 

so yeah is it a good or bad idea ? 

how bad is the bottleneck and will it affect the gaming experience with micro stutters and such turndowns ?

let me know what you guys think or have a better idea and please go in details explain as much as you can 

 

or i have a risky choice i can cheap up on the psu ''thermaltake smart rgb series" so i can put the money on rtx 2060s ?

or 8gigs of ram otherthan 16gb and spend the rest on a better gpu ?
