Verdict
The GTX 1080 Ti and GTX 1660 Super land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.
The GTX 1080 Ti's 11 GB of VRAM is a 5 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 250 W for the GTX 1080 Ti. That 125 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 GTX 1080 Ti edges it on raw VRAM, which carries more weight the longer you hold onto a card.
