Core i5-13600K with RTX 4070: Bottleneck & FPS

At 1440p, a Core i5-13600K + RTX 4070 build averages about 83 FPS in AAA games at High settings, with 1% lows near 65 FPS: heavily GPU-limited. The RTX 4070 is the limiting part at every resolution, so the 14-core Core i5-13600K (LGA1700) still has headroom for about 146 FPS and room for a faster card later. In esports titles such as CS2 or Valorant expect around 265 FPS, enough for a 240 Hz monitor, while CPU-heavy games like Microsoft Flight Simulator drop to about 79 FPS with a 23% CPU bottleneck. With ray tracing enabled, expect about 48 FPS at 1440p, so turn on DLSS or FSR to get back above 60.
