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

Healthy pairing

GPU-limited, which is normal: your graphics card sets the pace. The fastest GPU would unlock about +42% in demanding AAA games at 1440p gaming (median 80 fps today).

Compatibility

All checks pass

Power

PSU Excellent · 468W draw / 850W

Physical fit

GPU + cooler clear the case
