Try other models and your own priorities
Presets are starting points. Swap either side, then open Advanced weights only if you want to tune the formula directly.
09 · Alternative
A third option worth checking
The same scenario and market frame checks whether another currently priced model offers a cleaner trade-off.
Worth considering instead
ASUS PRIME Z690-P — same A-tier capability for Gaming Build, about $49 cheaper · Value 59.
Neither of the two above is the only answer — this one clears the same bar for less. ⇄ Compare all three
