Yeah, browser plugins can be a killer. On my old machine before I did some cleanup, Brave/Chrome could end up using 30gb of ram! This is for a million tabs of course, but each plugin is duplicated for each tab so it all adds up.

I recently bought an AMD RX580 4gb card for relatively cheap, which is VERY fast. Probably overkill for you. Look for something like an RX 550 or 560 4gb card or something in that range - they're probably more than powerful enough, and consumes much less power (and subsequently creates less heat and noise) than most other 4gb cards - my RX580 is ~180 watts while a 560 is ~75 watts.
