Also, an additional note on this topic, that may be a bit philosophical. If you are new to Blender, and 3D in general, you would need to ask yourself (as I am asking myself constantly): how likely it is, that you will really earn money with doing this? I’m not talking about being a billionaire from NFT-s kinda plans, or so, just really, down to the earth kinda way.
Most of us are hobby artists, and this hobby mostly takes money, time, etc… and never really brings them.
Ask yourself, if only your GPU or other specs are the factors, that would hold you back from actually earning more from this, than the amount you spend. Can you may out the capabilities your rig right now?
Can you not model, texture, bake or render reasonably without the need of a better machine? The answer is most likely yes. If you had a better rig, would you know better, how to model, or what nodes to plug where?
Of course, with a few subsurf, you can break any video cards but reasonably, mostly all of us are held back by time issues, and skill, and not our rig.
So, at the end of the day, ask yourself, if you really have a plan you are willing to follow. Selling assets, creating a Youtube channel, working as a freelancer maybe, and if you are dedicated and likely to reach that goal. And when you have that goal, and start working for it, and you really feel you need to spend some more money, that you will likely get back in 2-5 years, at least partially, then yes, you may need that upgrade, but even then, I would consider a more cost-effective approach, like an AMD 6800 compared to a 3070-3080. Blender will most likely improve AMD support in the future, that will give you an edge later, not just in gaming.
Until then, I would simply start doing Blender, tutorials, small assets, larger scenes for fun, and check what interests you, and if that may bring money later. For that, know your interests, and have a PLAN, other than occasionally creating some stuff. And if you really feel your rig is holding you back… well, then you can always check the market at that stage
