NEED MORE INPUT...
Namely, processor & RAM in addition to your graphics card for the bare basics in order to examine any potential performance issues. Noting the actual games you're playing, screen resolution & graphical settings will help as well. Without this information, I can only provide general information to assist you.
Since Radeon RX 570 has a performance equivalence of a Nvidia GTX 1060, it should run most games at 1080p @ 60 Hz at default settings with minimal issues (maintaining ~60 FPS). Some higher-end games like PuBg will want a higher-end card for default settings, but going beyond 1080p (like 1440p @ 120 Hz or even 4K @ 60 Hz) will require a higher-end card to maintain a 60+ FPS performance.
Your system will also need AT LEAST 8 GB's of RAM (as a bare minimum) to run most games comfortably. 16 GB's is generally the recommended amount (going beyond that can be a potential waste of money), but anything over 8 GB's can be helpful.
As for processors, you'll generally need a relatively current generation Intel Core-i5 / i7 OR an AMD Ryzen processor. Newer processors can be better optimized for performance compared to older processors of similar speed & core count. Intel Core-i3 processors are generally not recommended as they were dual-core processors (which some games refuse to run on) until the 8th Generation, when they were increased to quad-core. Intel Core-i9's & AMD Ryzen Threadripper processors can be considered overkill in terms of gaming.
Storage Drive isn't a considerable factor for in-game performance, but it does affect loading times. The traditional 5400 RPM HDD is generally decent, but gamers prefer the high-speed 7200 RPM HDD (~26% faster) for larger capacity drives (2-4 TB's). SSD's are highly desirable, but their costs & lower durability (drives have a general lifespan of 2-5 yrs with constant use, compared to 5-10 years of HDD's).
Usage of older or weaker components will result in performance bottlenecks (& major performance hits). Having a lot of programs running in the background can also attribute to performance hits as well as many games recommended closing all unnecessary programs in the process (keeping at least your security software & possibly the game launcher, like Steam, running).
Hope this sheds some light on the subject.
