Hi @techworker1 ,
If I were you, I would go for as much VRAM as you can afford. At least 8GB.
As far as I know, the difference between the 40xx and 50xx is mainly gaming optimisations in the 50 series. And (for instance) a better SuperSampling won’t do you any good in Blender and Video Editing. And I’d prefer 12GB DDR6 (in the 40 series) over 8GB DDR7, but that depends on the complexity of your Scenes (if you run out of VRAM, it’s speed doesn’t matter anymore).
Too bad you’ll have to switch to Windows11, but you’ll be getting an enormous boost anyway, by upgrading from the old 1060.
