Live benchmark data
Not enough verified runs yet for a fair pool verdict — averages appear once each side has at least five.
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.
Verdict — RTX 4070
One of the most efficient cards ever made — sips power, runs cool. VRAM is the weak point but adequate for most 1440p use. Used market often prices it well against a new 5060 Ti.
