Verdict
The RTX 3070 and RTX 5080 land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.
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.
If we had to pick one: the RTX 5080 edges it on raw VRAM, which carries more weight the longer you hold onto a card.
