It was mostly with single-core-heavy (i.e. older) games. Newer multi-core games did very well on the i5, but better still on the six core Ryzen. I mostly play older games so my experience is likely different from most gamers. Edit: An example from memory, the very old game Crysis stuttered badly at 1440p with the i5, it was only playable at 1080p (both resolutions with all graphics settings on highest/ultra); this was with the GTX 1060. When I first built the Ryzen system I carried over my GTX 1060, and was able to play that game at 1440p60 smooth as butter. Turning off vsync I was getting close to 100fps, whereas with the i5 and vsync off I was lucky to spike above 70, with average fps somewhere around 30-35. Moving to the RX 580 actually dropped the fps cap slightly with vsync off, but still allowed me to play at 60fps locked for a smoother experience overall. In general, this was the same experience with all of my older games (Skyrim, Far Cry 2, Mirror's Edge, Rust, etc). With newer multi-core games like Doom 2016 and Far Cry 4 I never had any CPU bottleneck on the i5, and the new system marked an increase in graphic quality without sacrificing smoothness and resolution.
