Your “humble brag” aside, yes, this will be adequate for you to learn/do 3D graphics. 
Actually, it sounds like far more than you’ll need, probably for quite some time. Just don’t get into the bad habit of over-building everything or going crazy with refracted lights or anything or you’ll eat up all that power in no time. In all my years of work, I have always had to pay close attention to optimizations of lights, models, layers, fx, everything! You need to only build what you need for your specific purposes.
I’m old school, though, and can’t figure out how anyone can use Max or AE on a 15 or 17" screen. I’d recommend plugging one or more 24" or 27" monitors into it. But then I’d recommend a tower over a laptop any day of the week: easy to cool, tons of bays/space, fat graphics cards, etc.
Also, there’s a hardware forum on this site just for these discussions, which is where this thread should be. When I figure how to move it there, I will.
And in the future, try to use more accurately descriptive thread titles so that people scanning the forums know what’s in your thread without having to open, and so the subject’s title can be searched using the search function.
