Verdict
With the RTX 3080 running 33% above the RTX 3070 — a $230.01 premium — the two cards sit in meaningfully different price brackets. The RTX 3070 wins on value unless the extra performance matters for your workload.
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.
Unless you specifically need what the RTX 3080 offers, the RTX 3070 is the stronger value at this price gap.
