is it slow because your hardware isn't good enough? even if you don't know a powerful pc you can still do low poly modelling
work your way up in modelling, low (less than 1k polygons), mid (less than 10k polygons), (then high poly models [15k+ polygons ]assuming your computer can handle it)
if you want to experiment with 3D models in games, you can just create your game controls now and a test map, and just snag a ready to go model over at sketchfab
>Should I just use the very famous Zbrush?
god no, if you are a 2D artist as you claim to be, then you should know that it's not the tools that will make you a better artist
