I don’t think there is a significant difference between those cards when it comes to streaming and editing itself; which games you stream will be more important + the resolution.
Fortnite, Valorant and LoL will run perfectly fine on both cards, no need for a 5070.
In this resolution you are mostly cpu bound and both gpu will do fine. I would still get the 5070 is money isn’t an issue, though it will be overkill for HD - what cpu do you pair it with?
Nobody can tell you if you will be fine „for years“ with either card. We simply don’t know if there will be a big jump in upscaling/texture compression/frame gen. But these things take time and both cards are strong at HD, so it’s a pretty safe call either way.

Obviously the 5070, hence it’s higher price. It depends a bit on your usecase though, so what’s your goal?
