Can this CPU and graphics card support all adobe softwares?

You may want to educate yourself about the individual system requirements for the programs. Yes, the system will support all Adobe apps, but what performance to expect wil ldepend on the type of project you are doing. playing multiple 4k strteams in Premiere has different requirements than doing VFX work in AE and at least where that is concerned, even an RTX 3080 is overkill for AE. It simply doesn't use that kind of GPU acceleration plus there's in general a ton of issues with RTX cards and Adobe software. 64 GB is plenty and if you stick with Windows Home, you can't have more, anyway, because it will only allow apps to use 64 GB. Anything more will require an explanation of what specific workflows you have in mind. just buying a beefs gaming PC doesn't mean it's a reliable workstation for professional work.
