Core i7-14700K with RTX 3080: Bottleneck & FPS

The Core i7-14700K and RTX 3080 leave the CPU with plenty of spare headroom at 1440p: about 88 FPS on average in AAA games at High settings, with 1% lows around 69 FPS. The RTX 3080 is the limiting part at every resolution, so the 20-core Core i7-14700K (LGA1700) still has headroom for about 158 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 281 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 85 FPS with a 21% CPU bottleneck. Its 10 GB of VRAM is fine at 1440p but gets tight at 4K High. With ray tracing on, expect about 46 FPS at 1440p.
