Verdict
The GTX 1660 Super and RTX 3080 land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.
The RTX 3080's 10 GB of VRAM is a 4 GB advantage over the GTX 1660 Super. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
Power consumption is a meaningful differentiator here: the GTX 1660 Super draws 125 W versus 320 W for the RTX 3080. That 195 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.
