Switching from XBOX, this decent?

I’ve never been really a computer person but i really wanna take content creation more seriously and i think building a pc for it is the move, i can spend around $1500 and this is what i came up with (i wanna stream and record games like Fortnite and marvel rivals) is there anything i should change? Im fine with lower graphics just want solid frames, also this disclaimer threw me off a but, any insight on that?
