Verdict
With the RTX 5080 running 75% above the RTX 3070 — a $1,378.44 premium — the two cards sit in meaningfully different price brackets. The RTX 3070 wins on value unless the extra performance matters for your workload.
The RTX 5080's 16 GB of VRAM is a 8 GB advantage over the RTX 3070. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
Unless you specifically need what the RTX 5080 offers, the RTX 3070 is the stronger value at this price gap.
