Hey so really just wondering how worth it is to upgrade my 3070ti to a 5070ti. the 5070ti is around 2k australian dollars

I dont play heappppps of new games but im very into making art/video editing and i just know doubling my vram will be worth it. really i didn't even need to post this but more than anything just curious on other peoples thoughts on the 5070ti

for reference my build is:

AMD Ryzen 7 9800x3d
64gb cl30 ddr5
3070ti
