Yes. Unlike ASIC's which is specialized mining hardware for a specific POW algorithm, modern GPU's are able to mine all types of POW algorithms, including many that can't be mined by ASIC's, at least for now. To mine Ethash type coins like Ethereum, you need GPU's with at least 3 GB of VRAM.
Are most new coins POW? Is POS the future? And can I probably run that from my home without blowing a fuse, I live in the US if that helps.
Most coins currently are POW. Nobody knows for sure what the future will bring but IMO, POW GPU mining isn't going away anytime soon. In fact I think it may become more mainstream. BBT did an excellent presentation and overview on the state of Crypto and insights of where POW mining is going. Highly worth watching even if you're not new to Crypto. The beginning is on PSU configurations for mining rigs.

Most households can easily run between 3-5 six GPU rigs. Another consideration is heat dissipation. Any more than 2-3 rigs and you're likely going to need to find a way to exhaust the heat buildup from mining.
