Live benchmark data
Not enough verified runs yet for a fair pool verdict — averages appear once each side has at least five.
Verdict — RTX 5090
If you have to ask if it's worth it, it isn't — this card is for people who want max settings and don't care about the cost. Requires a monster PSU and a case that can fit it. The performance gap over the 5080 is smaller than the price gap.
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.
