Processor
Intel Core i7-7700K @ 4.20GHz
Graphics Card
GeForce GTX 1070
Calculation Result
Your CPU is too weak for this configuration. This may cause performance issues.
Intel Core i7-7700K @ 4.20GHz and GeForce GTX 1070 combination results in a 13.60% bottleneck. We recommend upgrading your CPU to improve performance.

Estimated FPS at 1080p (high)
Ranges, not exact figures - identical builds vary by roughly a quarter in real use depending on drivers, thermals and background load.
Method: estimated from measured GPU baseline framerates and PassMark CPU scores, capped by whichever component limits first. Workload factors derived from the OpenML "fps-in-video-games" dataset (CC-BY, Sven Peeters).
Intel Core i7-7700K @ 4.20GHz + GeForce GTX 1070 — FPS by game and resolution
High preset. Each cell is a range; the label marks which component sets the ceiling. Blank cells mean this pairing has no measured data for that combination — nothing is estimated in.

How quality settings affect this build — Fortnite at 1080p
Dropping settings only helps while the GPU is the limit. Once the label reads CPU, lowering quality stops buying frames on this pairing.
| Preset | Estimated FPS | Limited by |
|---|---|---|
| Low | 175–292 FPS | GPU |
| Medium | 163–272 FPS | CPU |
| High | 138–229 FPS | GPU |
| Max | 98–163 FPS | GPU |
Bottleneck by resolution
Raising resolution shifts load from the CPU to the GPU, so the balance of this pairing changes with the display it drives. Note this measures imbalance, not speed — the lowest figure is usually the lowest resolution, which is not the one to play at. Read it alongside the limiting part.
| Resolution | Bottleneck | Limiting part |
|---|---|---|
| 1280x720 | 12.7% | CPU |
| 1366x768 | 12.8% | CPU |
| 1600x900 | 13.0% | CPU |
| 1920x1080 | 13.4% | CPU |
| 2560x1440 your setting | 13.6% | CPU |
| 3840x2160 | 16.4% | GPU |
| 5120x2880 | 18.9% | GPU |
| 7680x4620 | 25.2% | GPU |
