Verdict
With the RTX 5080 running 76% above the GTX 1080 Ti — a $1,403.43 premium — the two cards sit in meaningfully different price brackets. The GTX 1080 Ti wins on value unless the extra performance matters for your workload.
The RTX 5080's 16 GB of VRAM is a 5 GB advantage over the GTX 1080 Ti. 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 GTX 1080 Ti is the stronger value at this price gap.
