Best Gaming PC by Resolution
Your target display decides the build. Pick your resolution for the sweet-spot parts and the CPU-vs-GPU balance that suits it.

Quick Summary · TL;DR
1080p stresses the CPU (value builds shine), 1440p is the balanced enthusiast sweet spot, and 4K is GPU-bound (spend on the graphics card). Choose your resolution, then match the build.
Or choose by the games you play in the best PC for your game guide.
Resolution decides the budget split, not the total
Two builds at the same price can be completely different machines, and the thing that separates them is the monitor. Resolution changes which component the money should go to, because it changes which component runs out of capacity first.
1080p: the processor earns its keep
At 1080p the graphics card finishes each frame quickly, so the processor has to keep up with draw calls, physics and game logic at a high rate. This is the only resolution where a mid-range CPU visibly holds back a strong GPU, and it is where a high-refresh monitor is easiest to saturate.
1440p: the balanced case
The workload splits roughly evenly, which is why every pair verdict on this site is stated at 1440p and why it is the resolution we recommend as a default. A 12GB or larger card and a current mid-range processor land here comfortably.
4K: almost entirely the graphics card
At four times the pixel count of 1080p the GPU does nearly all of the additional work, and a processor two generations old stops mattering much. What does matter is VRAM capacity and memory bandwidth, because texture and frame-buffer demands scale with resolution rather than with frame rate.
The practical consequence: upgrading your monitor changes which upgrade you need next. Check the effect on your own parts in the bottleneck estimator, which applies separate resolution weights to each side, or read how those weights are derived in our guide to the model.
