Still running an m1 Mac mini right now, it’s a damn good machine, but the performance gains over the years on the m series chips haven’t really forced me to upgrade yet. As for gaming, I just use GeForce now to play my steam library and it’s awesome, it’s a really great combo. The 8GB of ram is lacking, but I’m using GFN and not pushing it too hard, it’s doesn’t really matter and I don’t notice any meaningful performance problems. I’m also not editing photos or videos, so that probably helps.
