Summary
With the AMD Ryzen 5 5600 paired to a GeForce GTX 1660 Super at 1440p, this is not a balanced gaming setup for modern AAA play. The 35% bottleneck points clearly to the GPU, and the reason is straightforward: 1440p pushes far more pixel load than the GTX 1660 Super can comfortably handle, while the Ryzen 5 5600 still has headroom left. The average of 32 FPS, with dips to 22 FPS and peaks around 42 FPS, matches that picture. In plain terms, the processor is ready to deliver more frames, but the graphics card cannot render them fast enough at this resolution. That said, calculator results are estimates rather than lab measurements, so exact game-to-game behavior will vary.
Performance Expectation
At 1440p, expect the GeForce GTX 1660 Super to be the performance ceiling in most demanding games. An average of 32 FPS means many newer titles will feel only just playable at reduced settings, and the 22 FPS minimum matters more than the headline average because those dips are what you notice during combat, city traversal, or heavy effects. The Ryzen 5 5600 should keep simulation, AI, and general frame delivery in good shape, so the weak point is not raw CPU throughput but the GPU's limited raster performance and 6GB VRAM. That VRAM limit is a nuance many guides skip: at 1440p, texture settings can trigger stutter before average FPS alone suggests trouble. In lighter esports titles, this pairing can still do well, especially if you lower settings aggressively.
Upgrade Advice
The numbers justify a GPU upgrade, not a CPU change. With a 35% GPU-side bottleneck and only 32 FPS on average at 1440p, the Ryzen 5 5600 is not the part holding this system back. If you want to stay at 1440p, moving up to a stronger graphics card will make a real difference in both average FPS and minimums. If an upgrade is not in budget yet, the practical fix is to target 1080p or use lower settings, especially textures, shadows, and post-processing. I would not advise replacing the Ryzen 5 5600 for this build unless you also plan a much faster GPU later. Right now, CPU money would produce very little visible benefit compared with a graphics upgrade.
Best Use Case
This AMD Ryzen 5 5600 and GeForce GTX 1660 Super combination makes the most sense for someone who mainly plays older games, competitive titles, indie releases, or cross-generation games and only occasionally uses a 1440p monitor. It is also a sensible budget build for general desktop work, light content creation, and gaming where image quality can be trimmed back without much concern. The CPU is strong enough that the system still feels responsive and well behaved outside GPU-heavy loads. If your goal is steady high-refresh 1440p gaming, though, this exact pairing is aimed too low on the graphics side.
Warning
The critical point here is not just that the GTX 1660 Super is slower at 1440p; it is that the low 22 FPS minimum can make frame pacing feel uneven even when the average looks tolerable on paper. That can show up as hitching in busy scenes rather than a constant smooth slowdown. Also, these calculator figures are estimates, not controlled benchmark data, so a well-optimized game may land above 32 FPS while newer heavy releases can fall below it.
