Core i7-11700K + RTX 3070 Ti: bottleneck check
Evenly matched at 1440p.
Neither part waits on the other at 1440p. This is as balanced as a pairing gets.
By resolution
| Resolution | Limiting part | Severity | Verdict |
|---|---|---|---|
| 1080p | CPU | 8% | balanced |
| 1440p | GPU | 1% | balanced |
| 4K | GPU | 23% | GPU-bound (normal) |
This is the classic pattern: at 1080p the Core i7-11700K is the limit (8%), while at 4K the RTX 3070 Ti takes over (23% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply
The RTX 3070 Ti measured 298 W average while gaming (350 W highest 20 ms spike, TechPowerUp). With the Core i7-11700K at its TDP of 125 W and about 75 W for the rest of the system, the sustained load is about 498 W. A 750 W unit is the safe choice; a good-quality 650 W unit also covers the measured draw. Details on the RTX 3070 Ti PSU page or try other pairs in the PSU calculator.
