Verdict
The RX 5700 XT and RX 6600 land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.
Power consumption is a meaningful differentiator here: the RX 6600 draws 132 W versus 225 W for the RX 5700 XT. That 93 W gap can determine whether your existing PSU is sufficient and will show up in long-term electricity costs.
Either card is a reasonable buy at this price level — availability and any bundled promotions should tip the decision.
