I saw something on it the other day
GeForce RTX 3070 has 5,888 CUDA cores with base/boost clocks of 1.5GHz and 1.73GHz, along with a great value proposition.

So not 100% sure I'd say its a full benchmark to go by, but I don't know if I'll pay for the difference you get with 3080.
....maybe. I'll need to see more.
edit. The system I'm building is actually based on my work as my PC is primarily used for graphic design, photoshop, clip studio, Sony Vegas etc. I simply always add a bit more to the budget to game on it. So I'm fine if I'm able to run it at decent settings as majority of my gaming will likely still be on console and handheld.
