So I was thinking of it was worth upgrading my Rog strix rtx3070to to the MSI rtx5070, would it be worth the upgrade?
CG Director is a good place to compare GPUs, for performance, price, and particularly price per performance comparison. This shows Redshift scores, but probably good for any application in terms of comparison.
If you can… reach for any rtx 4090… is still out performs all others even the 5090 however the 5090 comes close and has more memory.
