Is 5070 ti 16 GB Worth The Difference Compared To 5060 ti 16 gb

I will be upgrading my 4050 6 GB laptop and made a system like this for centered around stable diffusion. The only thing I was planning to ugrade later was ram amount but on here inno3d's 5070 ti 16 gb constantly goes on sale for around 150 dollars less from time to time. So I am not sure right now if I should buy lesser versions of my mother board and CPU and upgrade my GPU instead. I am also not sure how the brand inno3d as well because it's my first time building a PC and learning what is what so I only know the most famous brands.
