I may have very different uses for my PC than you (I use it primarily for gaming and my job as a game developer), but I find the notion of having to upgrade your PC to run a browser-based application very strange.
I am not saying that electron-based apps are generally good or efficient. Most of them are frustratingly slow and awkward. But this inefficiency rarely seems to be constrained by local resources: the apps often stand still, consuming barely any resources (CPU time, memory, etc.) and taking ages to load each page. At the same time you can often visit the same page in Chrome and it will load almost instantly.
It is frustrating and I have no idea what is going on, but it doesn't seem like upgrading the PC would solve the issue.
