Live benchmark data
Not enough verified runs yet for a fair pool verdict — averages appear once each side has at least five.
Verdict — RTX 5080
The reasonable enthusiast pick. 16 GB VRAM is enough for now but will feel tight in a couple of years for 4K modded games. Runs cool and quiet compared to the 5090.
Verdict — RTX 4090
If you already have one, keep it — it's still a top-tier card. If you're shopping used, weigh it against a new 5080; the used discount needs to be significant to justify the older architecture.
