Target prices are calculation thresholds under today's dataset; where none exist, the row says so instead of showing blanks. Recalculated on every data refresh.

FAQ
- What is a good price for the ASUS PRIME X870-P-CSM right now?
- The price targets at the top of this page are calculation thresholds, not forecasts: they say what the competing offers in the 2026-09-11 frame would have to be beaten by under the balanced weighting. Two caveats worth knowing — they move when the rest of the market moves, even if this product's own price doesn't; and hitting a target says the PRICE is good, not that the product suits your job (that's what the tier badges above answer). Change the weighting in the calculator and the targets change with it.
