How to improve · 9 pts to B

Valuecosting ~12 pts

Biggest non-performance spend: memory (+$249 over a solid baseline) — shifting that toward the GPU buys more frames.

CPU/GPU balancecosting ~7 pts

CPU-limited — measured at the 1080p reference, a faster CPU would unlock about +33% from the GPU you've chosen (median 63 fps today). CPU: entry-level, GPU: mid-range.

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.
