Will a Ryzen 3 3100 bottleneck a GTX 1070 Ti?

A Ryzen 3 3100 can run a GTX 1070 Ti, and it’s a decent budget combination if you already own the parts. However, the 3100 is a fairly weak choice by current standards, so a Ryzen 5 from the same generation or a newer affordable CPU would give you better minimum frame rates and more room for future upgrades.

The pairing should work reasonably well, especially at 1080p or higher, but the exact balance depends on the games and frame rate you’re targeting. At very low resolutions or with high-refresh-rate gaming, the Ryzen 3 3100 may become the limiting part. There will always be a bottleneck somewhere; the goal is simply to keep it from hurting performance too much.

The 1070 Ti is still capable for many 1080p games, but check the current driver situation and game requirements before buying one. More importantly, share the games you play, your target resolution, and your monitor’s refresh rate—those details matter much more than the word “bottleneck” by itself.
