Is it possible to upgrade my laptop so i can livestream while gaming and putting my vtuber model in the OBS all at the same time smoothly?

Man so I used vseeface to create my vtuber model, and I use OBS, when I put the game capture to put the game on obs and then put another game capture to put my vtuber model in OBS, not only does it slow down the game by a lot but every time i try to livestream the internet connection is shit, it won't connect to the OBS and when it does it buffers a lot, so what do i need to do? get a better RAM for it? buy a new laptop? I'm putting my specs in the comment section
