Biggest non-performance spend: memory (+$291 over a solid baseline) — shifting that toward the GPU buys more frames.

Why these are estimates?

These numbers are model-predicted averages, not measured benchmarks of your specific system. Treat them as ballpark guidance, not a promise. Real framerate depends on:

Your full system (RAM speed, storage, drivers, OS, background load)
In-game scene complexity, multiplayer player count, mods
Driver updates and game patches after this estimate was made
Display, thermals, and how your case manages airflow

If you want a measured number for your specific build, the only reliable answer is to benchmark it yourself once you own the parts.

Balance

CPU-bound (17%)

Both CPU and GPU sit at estimated high-end, but 1440p gaming leans on the CPU — a stronger CPU at this GPU tier would unlock more frames. We don't have FPS data for either of these chips yet, so this is a spec-based estimate, not a measured verdict.

Compatibility
