Live benchmark data
Not enough verified runs yet for a fair pool verdict — averages appear once each side has at least five.
Verdict — RTX 5070
Competent card that would have been great with 16 GB. As-is, expect to lower texture settings within 2–3 years to avoid stutter. Consider the 5070 Ti if budget allows.
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.
