Verdict
With the RTX 5090 running 89% above the RTX 2080 Ti — a $6,625.99 premium — the two cards sit in meaningfully different price brackets. The RTX 2080 Ti wins on value unless the extra performance matters for your workload.
The RTX 5090's 32 GB of VRAM is a 21 GB advantage over the RTX 2080 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 5090 offers, the RTX 2080 Ti is the stronger value at this price gap.
