02 · Decision matrix

One decision, three separate questions

Capability ignores price. Relative Value adds the current dataset offers and your priorities. Keeping them separate prevents a cheap product from being mistaken for the faster product.

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
MSI PRO B650M-B — same A-tier capability for Gaming Build, about $62 cheaper · Value 28.
