Question Will the Ryzen 7 3700X bottleneck the RTX 2070 SUPER?

In real life average gaming its actually not likely that anyone experiences any significant bottleneck with any modern components.

If you have 2080ti, game only at 1080 on medium-high quality, also have a 240hz monitor, never will use raytracing, and need that 240FPS in every title you play for whatever reason you think you might need it - then you should be worried about a CPU bottleneck knocking a few FPS off your top end.

If not, then the consideration doesn't really apply and you should be more concerned with GPU performance.
