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 3080
Great card in its era. If you have one, keep it — it's still perfectly capable. Newer cards match its performance at half the power draw.
