Verdict
The RTX 3070 and RTX 3080 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 RTX 3070 draws 220 W versus 320 W for the RTX 3080. That 100 W gap can determine whether your existing PSU is sufficient and will show up in long-term electricity costs.
If we had to pick one: the RTX 3080 edges it on raw VRAM, which carries more weight the longer you hold onto a card.
